Connact Sören if there is the need to exchange a module. However, the differences in the configs are only the hostname. (**To be tested: On the fly might work, if one edits the config-file itself after switching of the server instead of selecting another config file in the GUI. But how to transport this information to the GUI? → Display the first line of the config file!**) The config files are located at the **hasfl2det01: /export/doocs/server/gotthard_server/cfgs/**

161		-== Triggering the Gotthard with a burst trigger ==
162		-
163		-it is also possible to trigger the Gotthard not only with 10 Hz but with a burst trigger
164		-
165		-here are some Info from PIS (June 2023)
166		-
167		-
168		-
169		-{{view-file att--filename="Flash_G1.pdf" height="250"/}}
170		-
171		-I think one does not need to set it in GUI when running in continuous mode. In G1, whether the detector is running in burst or continuous mode depends on the setting of the "number of frames" in trigger mode. If the number of frames sets to 1, it will be in continuous mode (1 trigger -> 1 frame).
172		-
173		-Since G1 accepts triggers from the lemo connector, one can also use the bunch train trigger. The spacing of the trigger train needs to be larger than 3.2 ms, which is the readout time of G1.
174		-
175		-Regarding the detector setting (assuming it is 200 kHz pulse rate, 100 pulses per train):
176		-
177		-* timing mode: trigger
178		-* number of frames: 1
179		-* number of triggers:  M x N (M is the number of trains and N is the pulses per train, one can also take a bit more frames per train to track the pedestal/dark)
180		-* period: < 5 us (1/200 kHz = 5 us, the period needs to be slightly smaller than 5 us since the detection of the trigger only starts after the period is reached)
181		-* exposure time: > 93 ns and smaller than period
182		-
183		-Alignment: One of the four lemo connectors on G1 outputs its exposure window. Using an oscilloscope, one can use a photodiode under the beam and align the pulses from the diode and the exposure window of G1 by fine tuning the exposure time of G1 and/or the setting of "delay after trigger" from the detector, or "delay time" of the wave-generator (if a wave-generator is used to generate the triggers for every pulse). After this, one can do a fine scan of trigger delay to find an optimal setting with highest signal after putting G1 under the beam.
