Wed May 29 10:54:21 2024, Shahab, Jan, General, Gas Target Events with new timing system 
|
Using the new timing system, it is possible to grab any events as pulses, but also as long inter event gates under GENESYS. Many instances of GENESYS can
be running on ACO computers, so that there is no conflict, if an instance is running in main control room or another in ESR-Messhütte.

We changed the dye at ~3pm.
After some fine adjustements of the laser we had to change the MRC settings, because the laser position changed.
