<h4> <span style="color: red;">T</span>ime of Flight Measurement for <span style="color: red;">I</span>njector and Ring Cyclotron Turn <span style="color: red;">N</span>umber <span style="color: red;">A</span>scertainment, <span style="color: red;">TINA</span></h4>
<h2 style="color:blue;">About</h2>
<p>The TINA application determines the number of turns in a cyclotron
from a Time of Flight (TOF) measurement technique and a cross-correlation
of fast sampled data from capacitive sensors located at the entrance and exit
of the cycolotron. This is based on a python implementation of a LabVIEW application developed by
Pierre-Andr&eacute; Duperrex: <br>

<h3 style="color:#7b68ee;">Changelog</h3>
August 2025: Hilbert transform applied to signals.
<!--a href="page1.html">here</a></p-->
<h2 style="color:blue;">The Repository</h2>
<p>The application comprises two components:
<ul>
<li>
The low-level ADC data acquisition system is detailed in the following repositories:<br>
<span style="color: green;">https://git.psi.ch/GFA/CO/general/CPSI_SCOPE/CPSI_SCOPE</span><br>
<span style="color: green;">https://git.psi.ch/epics_iocboot_hipa/z_di_turn_count</span><br>
</li>
<li>
A High Level Application (HLA) that is able to interact with the IOC, start a low-level data acquistion run,
acquire the raw data, and perform the number of terms analysis.<br>

The Oscilloscope option disables setting values to epics process variables and is meant for testing code with raw data collected from the oscilloscope and stored in hdf5 files: <br>
/hipa/bd/data/measurements/Tina_2024-09-18_oscilloscope.h5
<p>
<h4 style="color:#7b68ee;">Procedure</h4>
Within the Procedure group, the Start button executes the analysis program
which usually takes less than 10 seconds to complete. 3'010'560 samples are
collected per channel (entry wf/exit wf).
<p>
The SaveAll button:
<ul>
<li>writes the number of turns measured into an epics process variable,
</li>
<li>save the raw data to hdf5,
</li>
<li>opens a dialog window for submission to the selected elog book.
</li>
</ul>
These actions can also be executed individually through icons placed in the menu bar.
<p>
<font color=green>
Data can be recalled from hdf5 and reanalyzed using the HDF analysis functionality
made available through a docked widget in the menu bar (right click on the menu bar
and select the HDF5 option).
