# cSAXS BEC
|
|
|
|
cSAXS specific plugins and configs for BEC
|
|
This document guides you through the procedure to spin up BEC at the beamline for a new experiment (e-account).
|
|
You might want to run cSAXS copy scripts before in case you want to have the former data structure to be preserved.
|
|
|
|
## Overview
|
|
|
|
- Clone cSAXS BEC repository into e-account (e.g. into ~/Data10/software/.)
|
|
- Start Epics iocs
|
|
- Start BEC, BEC server and load/modify the device config with relevant hardware
|
|
- BEC commands
|
|
|
|
## Clone cSAXS BEC repository
|
|
|
|
Clone the current cSAXS BEC repository from GIT into the new e-account.
|
|
Create directory
|
|
```bash
|
|
mkdir ~/Data10/software
|
|
cd ~/Data10/software
|
|
```
|
|
Clone repository
|
|
```bash
|
|
git clone https://gitlab.psi.ch/bec/csaxs_bec.git
|
|
```
|
|
## Start epics iocs
|
|
|
|
You can start up the iocs while the *./setup_bec.sh* script is running. Be aware though that the scripts requires you to interact with it.
|
|
|
|
### DelayGenerator
|
|
|
|
Open a new tab in a terminal in comp1/comp2 or cons1 and follow the commands below:
|
|
``` bash
|
|
ssh gac-x12sa@localhost
|
|
cd ~/delaygen
|
|
iocsh -7.0.6 startup.script
|
|
```
|
|
Be aware -7.0.6 is referring to the current epics version and might change in future (SLS 2.0).
|
|
To start the epics panel (only if needed), run in a new shell
|
|
``` bash
|
|
caqtdm -noMsg -macro P=delaygen:,R=DG1: srsDG645.ui
|
|
```
|
|
|
|
More notes on usages and cabelling of DDGs.
|
|
Currently 3 generators are used:
|
|
- DDG1 for detectors (EXT Enable from SGalil stages, T0 to DDG2, AB for eiger, CD for Falcon, EF for Pilatus_2)
|
|
- DDG2 for mcs card (ext. enable from DDG1, AB to mcs card)
|
|
- DDG3 for fast shutter and mcs enable (AB short pulse to enable MCS (needed!!), CD to keep FSH open )
|
|
|
|
### Eiger
|
|
|
|
Open a new tab in a terminal in comp1/comp2 or cons1 and follow the commands below:
|
|
``` bash
|
|
ssh gac-x12sa@localhost
|
|
cd ~/Software/Eiger/
|
|
./launch_ioc
|
|
```
|
|
A live view of status and images for std_daq can be found here [xbl-daq-29:5000](xbl-daq-29:5000).
|
|
|
|
### Pilatus_2
|
|
|
|
First, start the cam server.
|
|
Connect to the computer and follow the instructions printed after connecting:
|
|
``` bash
|
|
ssh det@x12sa-pd-2 (Pilatus2)
|
|
```
|
|
The cam server will open, wait until you see **.
|
|
Nex step, open a new tab in a terminal in comp1/comp2 or cons1 and follow the commands below:
|
|
``` bash
|
|
ssh gac-x12sa@localhost
|
|
cd ~/Software/Pilatus300K/
|
|
./launch_epics
|
|
```
|
|
### FalconX1
|
|
|
|
Open a new tab in a terminal in comp1/comp2 or cons1 (logged in as the current e-account) and follow the commands:
|
|
``` bash
|
|
ssh x12sa-cons-01
|
|
cd /ioc/X12SA-PC-FALCONX1/
|
|
iocsh -7.0.6 startup.script
|
|
```
|
|
Be aware -7.0.6 is referring to the current epics version and might change in future (SLS 2.0)
|
|
|
|
## Start BEC, BEC server and load device config
|
|
|
|
Step 1 needs to have finished for continuing with these steps.
|
|
What remains now is to start the bec server. Connect to pc15543 and open a new terminal to run:
|
|
``` bash
|
|
cd ~/Data10/software
|
|
source bec_venv/bin/activate
|
|
bec-server start
|
|
tmux attach -t bec
|
|
```
|
|
|
|
Open another teminal on pc15543 and start BEC:
|
|
``` bash
|
|
cd ~/Data10/software
|
|
source bec_venv/bin/activate
|
|
bec
|
|
```
|
|
|
|
Note: In case there is a warning after starting BEC that it was not able to import *scilog*, you will have to pip install scilog in the bec_venv to be able to send printouts to scilog from the command line.
|
|
Within a new terminal:
|
|
```bash
|
|
cd ~/Data10/software
|
|
source bec_venv/bin/activate
|
|
pip install scilog
|
|
```
|
|
|
|
Device config from csaxs-bec plugins
|
|
```bash
|
|
bec.config.update_session_with_file('/sls/X12SA/data/e20639/Data10/software/csaxs-bec/bec_plugins/configs/bec_device_config_sastt.yaml')
|
|
bec.config.save_current_session('~/Data10/software/current_config.yaml')
|
|
```
|
|
The second command is helpful if you adjust limits of motors, which will then be stored in the config and loaded if a reload of the configuration is needed.
|
|
|
|
## BEC commands
|
|
|
|
A number of commands that are useful:
|
|
|
|
To move devices that are added in the config:
|
|
```bash
|
|
umv(dev.samx, 0) #absolute
|
|
umvr(dev.samx, 0) #relative
|
|
dev.samx.wm #print motor position and limits
|
|
dev.samx.limits = [low_limit, high_limit] # To set limits, note, same lower and higher limit, e.g. [0, 0] means no limits!!
|
|
```
|
|
Scans:
|
|
```bash
|
|
scans.acquire(exp_time = 0.5, frames_per_trigger=10, readout_time=3e-3) # equivalent to a loopscan 30 0.5
|
|
scans.line_scan(dev.samx, -1, 1, steps=20, exp_time=0.5, readout_time=3e-3, relative=True) # optional, add frames_per_trigger =10 for burst acquisition at each step
|
|
#Scan 2 motors in a step scan at the same time
|
|
scans.line_scan(dev.samx, -1, 1, dev.samy, -1, 1, steps=20, exp_time=0.5, readout_time =3e-3, relative=True) # step scan with 20 steps, again frames_per_trigger can be added for burst at each point
|
|
scans.sgalil_grid(start_y = , end_y = , interval_y = , start_x=, end_x=, interval_x =, exp_time=0.5, readout_time=3e-3, relative=True)
|
|
```
