11.00 - chiller refilled and switched on
        set to 20 degrees celsius

AIDA stand moved and secured in F11
        clock connected -> 50 MHz square wave at 5.0 V

AIDA connected to power box
        network cables attached
        NIM modules switched on

Raspberry Pis switched on
        Detector bias switched on for detectors 1-6
     
        
        
13.58 - AIDA power relay 1,2,5,6 sequenced on
       bias/leakage currents ok (attachment 1)
       DAQ setup
       System wide checks ok, except naida07 fails ADC calibration, and clock status check returns error in
nnaida06, 5.

Above issue with clock no longer present

FEE temperatures ok (attachment 2)
       good event statistics (attachment 3)

16.30 1.8.W spectra n+n strips
      FSR 20us, 200us, 2ms, 20ms attachments 4-7

1.8.W spectra p+n strips
      FSR 20us, 200us, 2ms, 20ms attachments 8-11
       
      compare with https://elog.ph.ed.ac.uk/AIDA/746

naida19, naida20, naida23 show low frequency noise structure, worse than in above elog entry
