* Moved setup into case with optical breadboard
* 2 holes on case to feed cables out of photodiodes
* Will need optical board with standard hole pitch, height: 15 cm from detector to board
* 30 cm x 25 cm area on board to bend cables comfortably
* 1 cm diameter hole required for the cables
* Current tracker design has circuit boards going opposite directions - due to thickness of glue of connectors of diodes to board to protect them
* Can potentially look at having this sorted for next prototype as well having mounting of board parallel to fibres rather than perpendicular
* 5V supply, two clocks from fpga, ground, digital output - trigger with ground I.e. not all cables of ribbon cable not used
* End of ribbon connects to fpga
* NI to PC via usb
* Fpga uses microusb (fpga side) and usb c (laptop side)
* Try to replicate daq setup in icl (Simon believes we have another NI setup here)
* Febian to setup Labview on the DAQ laptop he's using - available from ucl software database
* Sonia to look in office from NI DAQ box - check whether screw terminals or BNC connectors - also check for zybo
* Raffy's NI DAQ model- NIUSB6356
* Raffy will travel with everything except optical breadboard
* Planning to have protection for setup on next prototype

* Scintillator status update - martin email - more info this week
** Harry needs to test diamond cutter - organised in next few weeks hopefully
* File structure for raw, calibrated and fitted files - add 4th folder which contains shoot through and background (date_runnumber_background). Need to figure out calibration if. To taking calibration measurement for every run.
** Date and time on pi5 only updated when connected to internet so adding date and time to file name sometimes incorrect
** Need RTC module needs to be able to be powered by J5 (BAT) connected in order to do so - talk to Matt to discuss this - coin battery holders with external connections looks clunky
* Calibration code - issue with photodiode position issue fixed.
** Notice differences between manually measured value stackThickenss and sum of individual sheet thicknesses
* GUI DAQ: when device was not connected was displaying incorrect error messages - fixed now. Except one folder that is not completely corrected - need fpga and board to test with these changes. Should eb spare nexus in stack board in d109
* GUI Replay: issue - new file is always generated but correct graph is not always updated - maybe doesn't read from the file all the time - trying to correct to m make sure its reading every microsecond
** Replay of calibrated data - will set replay rate (display rte always 25 hz) but chose rate for calibrated data I.e. chose how much data is being averaged over (drop menu with a range of values from 25 Hz, 50 Hz, 100 Hz up to 5kHz (raw)) if anything other than raw need to calculate no. of frames to avg over etc.
** Hard code real-time fitting rate of 25 kHz and hide from gui
** May in future want checkbox that does fitting at set frequency in background

* Waiting for new zmod
* Started doing fitting from basic linear regression up to Bragg peak fitting
* Next step - meet Noki Komura in matts office - for tips in how to code curve fitting in fpga -
* Using nexus but has slightly more horsepower than usb
* Doing practice fitting in fpga simulation
