The following measurements were done to demonstrate the performance that can be
- obtained with the areaDetector Pilatus driver.
-
- - AcquireMode=Internal, NumImages=1000, AcquireTime=.005, AcquirePeriod=.01, NumExposures=1.
- The time to collect this series should be exactly 10.0 seconds. The actual time
- was measured using the EPICS camonitor program. It printed the time when acquisition
- was started (Acquire changed to Acquire=1) and when acquisition was complete (Acquire
- changed to Done=0). The time was 10.022 seconds. This includes the time for camserver
- to save all 1000 images to disk (366 MB), and for pilatusROI to read each file,
- correct the bad pixels and flat field, compute the ROIs, and post the ROIs to EPICS.
- It also posted all of the images to EPICS. The total additional time was less than
- 0.03 seconds for all 1000 images.
- - AcquireMode=Internal, NImages=1, ExposureTime=.01, NExposures=1. An EPICS sscan
- record was used to collect 1000 points. There were no positioner PVs (to eliminate
- motor overhead). The only detector trigger was the Pilatus Acquire PV. The only
- detector PV was ROI1:0:Total_RBV. In this mode camserver is being told to individually
- collect each file. If there were no overhead then time to collect this series should
- be exactly 10.0 seconds. The actual time measured using the EPICS camonitor program
- was 45.514 seconds. The overhead is thus 35.514 seconds, or 35 ms per point. In
- this single-frame mode pilatusROI is thus able to collect >20 images/second. For
- comparison, another measurement was done using the same EPICS sscan record, but
- using a Joerger VSC16 scaler as the detector trigger and detector. The preset time
- was also .01 seconds. The elapsed time for a 1000 point scan was 16.068 seconds,
- so the overhead was 6.068 seconds, or 6 ms per point.
- - AcquireMode=Ext. Enable, NImages=1000, NExposures=1. SPEC was used to collect
- 1000 points using
- trajectory scanning mode with the Newport XPS motor controller. The following
- SPEC command was used:
-
lup chi -2 2 1000 .015
-
- This tells SPEC to do a relative scan of the chi axis from -2 degrees to +2 degrees
- with 1000 points at .015 seconds/point. On our kappa diffractometer this entails
- a coordinated motion of the phi, kappa and omega axes. The EPICS trajectory scanning
- software downloads the non-linear trajectory that SPEC computes into the XPS controller,
- which executes it. As the motors are moving the XPS outputs synchronization pulses
- at the period of the collection time, .015 seconds in this case. These pulses are
- stretched (see Hardware notes below) and used as the
- external input to the Pilatus. The time to execute this scan should be 15.0 seconds.
- The actual time was 16.3 seconds, measured using camonitor on the Acquire PV. Again,
- this includes the time for camserver to save all 1000 images to disk (366 MB), and
- for pilatusROI to read each file, correct the bad pixels and flat field, compute
- the ROIs, and post the ROIs to EPICS. It also posted the images to EPICS at 1Hz
- (15 images total). The total additional time was less than 1.3 seconds for all 1000
- images. As soon as the acquisition was complete SPEC plotted the net counts in the
- first ROI (containing the Bragg peak) as follows:
-
-
- 1000 point SPEC scan with 15 ms per point collected in 16.3 seconds
-
-
- For comparison this identical scan was executed in traditional step-scanning mode,
- where the motors stopped at each point in the scan. The Pilatus was run in Internal
- mode with NImages=1. The total time for the scan was 870 seconds (more than 14 minutes),
- compared to 16.3 seconds in trajectory mode. Most of this overhead is the settling
- time for the motors, with only a small fraction due to the Pilatus single-exposure
- mode. The trajectory scanning mode is thus more than 50 times faster to execute
- the identical SPEC scan.

- The Pilatus supports 3 types of external triggering. In External Trigger mode (the
- camserver ExtTrigger command) the Pilatus uses the programmed values of ExposureTime,
- ExposurePeriod, NImages and NExposures. It waits for a single external trigger,
- then waits for Delay seconds and then collects the entire sequence. It is very similar
- to Internal mode with NImages>1, except that it waits for a trigger to begin collecting
- the sequence.
-
- In External Enable mode (the camserver ExtEnable command) the Pilatus uses the external
- signal to control acquisition. Only NImages and NExposures are used, ExposureTime
- and ExposurePeriod are not used. When the signal is high the detector counts, and
- on the transition to low it begins its readout.
-
- In External MultiTrigger Mode (the camserver ExtMTrigger command) the Pilatus uses
- the programmed ExposureTime, in addition to NImages and NExposures. Each external
- trigger pulse causes the Pilatus to collect one image at the programmed exposure
- time. This mode works well with a trigger source like the Newport motor controllers
- or the SIS380x multichannel scaler, that put out a short trigger pulse for each
- image. One only needs to take care that the time between external trigger pulses
- is at least 4msec longer than the programmed exposure time, to allow time for the
- detector to read out before the next trigger pulse arrives.
-
- When using the External Enable mode, we use an inexpensive analog pulse generator
- to convert the trigger pulses from the MM4005 and XPS to a form suitable for External
- Enable mode with the Pilatus. This is the solution we have developed that seems
- to be reliable:
-
- - The synchonization pulses from the Newport MM4005 or XPS controller are input
- into the external next pulse (channel advance, control signal 1) input of the SIS3801
- multiscaler. This is the normal configuration used for MCS counting without the
- Pilatus in trajectory scanning mode.
- - The Copy In Progress (CIP) output of the SIS3801 (control signal 5) is connected
- to the Trigger Input of a Tenma TGP110 10 MHz Pulse Generator. CIP will output a
- pulse whenever the SIS3801 does a channel advance, either in external mode with
- the motor controller pulse input, or in internal timed channel advance mode. The
- TGP100 Pulse Generator is configured as follows:
-
- - Trigger Input connected to CIP output of SIS3801.
- - Triggered mode.
- - Complement output.
- - Pulse duration set with knobs to 3msec.
- - TTL Output connected to the External Input of the Pilatus.
-
-
- - With this configuration the SIS3801 CIP output is normally at 5V, and outputs
- a 0V pulse 1 microsecond long. The trailing (rising) edge of that pulse triggers
- the TGP110. The TGP110 TTL output is also normally at 5V, and outputs a 0V pulse
- 3 milliseconds long each time the SIS3801 pulses. That output is connected to the
- Pilatus External Input. In External Enable mode when Pilatus External Input is high
- the Pilatus is counting. When the External Input is low the Pilatus reads out. The
- readout time is set via the knobs on the pulse generator to be 3 ms, which is close
- to the minimum time allowed on the Pilatus.
-
-
- The Tenma TGP110 seems to be currently called a Tenma 72-6860, and lists for about
- $350 new at Newark.

- Detector Voltage
-
- When we were initially testing the Pilatus in the lab, we had many errors in External
- Enable mode, where it did not seem to be seeing the external pulses. camserver would
- get DMA timeouts, and need to be restarted. Dectris said these were happening because
- the cables on our detector are longer than normal, and the voltage drop from the
- power supply to the detector was leading to marginal voltage values. They suggested
- shortening the cables or increasing the supply voltage slightly. When moving the
- detector to the hutch these problems initially went away. However, they then recurred,
- and we fixed the problem by increasing the power supply voltage from 4.4 to 4.7
- volts at the detector.
-
- Dectris has since informed me that they have increased the power supply voltage
- on all new Pilatus systems, so this should no longer be an issue.

Restrictions

+ The following are some current restrictions of the MarCCD driver:
- - Limited to TIFF file format. camserver can save files in other formats, but pilatusROI
- can currently only read TIFF files. Furthermore, it has a very simple TIFF reader.
- It does not read the TIFF tags at all, but simply assumes that there is a 4096 byte
- header, followed by the 32-bit image data. The size of the image data is controlled
- by the NXPixels and NYPixels PVs, which thus must be correctly set.
- - The EPICS IOC should be run on the same computer as camserver. This is not strictly
- necessary, and places a small additional load on the CPU and network on that computer.
- However, we have found that TIFF files are available to be read within 10ms after
- camserver says they have been written if the IOC is running on the same machine
- as camserver. This is true even if the files are being saved on a remote NFS or
- SMB file system. On the other hand, if the IOC and camserver are running on separate
- machines, then the filesystem can wait up to 1 second after camserver says the TIFF
- file has been written before the IOC can read it. This is true even if the files
- are being written to the computer that the IOC is running on! This 1 second delay
- is often unacceptable for fast single-exposure scans, i.e. with NImages=1.

- The MarCCD driver keeps retrying to read each TIFF file until the modification date of
the TIFF file is after the time that the exposure command was issued. If
it did not do this check then it could be reading and displaying old files that
happen to have the same name as the current files being collected. This check requires
that the computer that is running the soft IOC must have its clock well synchronized
with the clock on the computer on which the files are being written (i.e. the computer
generating the file modification time). If the clocks are not synchronized then
- the files may appear to be stale when they are not, and pilatusROI will time out.
- pilatusROI actually tolerates up to 10 second clock skew betweeen the computers
+ the files may appear to be stale when they are not, and the driver will time out.
+ The driver actually tolerates up to 10 second clock skew betweeen the computers
but any more than this may lead to problems.
- - The Abort PV does not always work because camserver does not reliably implement
- the "K" command to stop an exposure sequence. In particular with NImages>1 camserver
- seems to often ignore the K command completely, even with exposure times/periods
- as long as 10 seconds. With NImages=1 it does kill the exposure after a few seconds.
- - The following items are hardcoded in the SNL program. They can be changed before
- compiling if necessary. Some could be changed to be EPICS PVs, so they could be
- controlled at run-time, but others must be defined at compile time because of limitations
- in the SNL semantics.
