The key is located at /home/tct/.ssh/ at the file TCTSetup_uzh.pub. The generic account associated withe the setup at the uzh cluster is tctsetup@linux.physik.uzh.ch coupled with centrally manged storage at /disk/data7/tctsetup. Data are backed up one per week. Connection is performed without the use of the password since the public key is already in the server authorization table and the connection parameters have been setup at the ssh configuration file. The connection is named //UZHServer//
 +From a bash command prompt one can simply type: **//ssh UZHServer//** 
 + 
 +The allocated storage at /disk/data7/tctsetup is automatically mounted at startup to the TCT_setup computer at /home/tct/UZHServerData via SSHFS. The location can be accessed as any other folder in the system and data taking scripts should be set to save data to that location be default. 
 + 
 +To copy pre-existing data to the server please use:  
 +rsync -avh --progress <current data folder> /home/tct/UZHServerData 
 +This will endure recursive directory copy and will validate files while displaying progress of the operation.

   - Manually locate the four corners by adjusting the position of the sensor using the software. Increasing the position in the positive x-direction shifts the plate towards the right side of the box, and increasing the position in the positive y-direction shifts the plate towards the back of the box. Once at the corner of an active region, the observed waveform amplitude will decrease and totally disappear.   - Manually locate the four corners by adjusting the position of the sensor using the software.

   - Once the four corners have been located, shine the laser somewhere in the middle of one of the four quadrants. There is a macro script to run which adjusts the z position (height) of the laser while measuring the voltage. Using this, we can find out the optimum distance the laser should be from the sensor.   - Once the four corners have been located, shine the laser somewhere in the middle of one of the four quadrants.

 +  - Alternatively, one could run a preview scan once some signals have been detected on the oscilloscope to locate the center of the sensor with greater precision. As shown in the example picture below, which is the preview 2D heat map of the voltage readout from one of the two channels of the daughter board, the position can be determined by hovering the mouse over the center of the slide.
