  • Charge

• RevE, SN_14, 2019.04.03 - Final

  • Calibration

  • Noise

  • Phonon

    • Ch.8 and Ch.9: We don't see the sine wave clearly in I. Multi Channel Signal Source.
    • Ch.8 and Ch.9: There is no trigger in III. Trigger - Tigger Signal (Feedback) .
    • Not trigger in IV. Test Signal Trigger .

  • Charge

    • We hade to lower the threshold from 2000 to 500 (FIR output unit) to get triggers.

• RevE, SN_12, 2019.03.27

  • Noise

    • All four charge channels are railed.

  • Phonon

     

• RevE, SN_8, 2019.03.08

  • Phonon

    • Input Gain: Good

    • Drive Gain: Good

    • Feedback Source: Good

    • PreAmp Source: There is variation among channels. Different phonon channels show different amplitudes corresponding to same test signal with the same driver gain and input gain. Test signal: Sine wave.

    • Trigger Test:

      1. Input Gain and Driver Gain both work on the input pulses
      2. Good with feedback source except for the cross-wired channels, pch0&pch1, pch4&pch5, pch8&pch9.
      3. Good with PreAmp source
      4. Test Signal Tigger is good, only pch0 tested. Didn't see sine wave in the last plot.

• RevE, SN_8, 2019.02.21

  • Charge

    • Offsets: Good
    • Trigger test with pulser: Good
    • Trigger test with input pulse: Good

• RevE, SN_8, 2019.02.01

  • Charge

    • Checked the offsets
    • Trigger tests are done for all four charge channels. Notes: Commented out assert amax(FIRdat[0]) == trigs[0]['amplitude'] in trigger tests, both with pulser and with input signal.

• RevE, SN_8, 2019.01.10

  more details description, check this google sheet.

  • Noise :

    • regular peaks in phonon channels, otherwise just ''flat'' noise
    • ugly noise in charge channels. you will see the noise with a wider range in Charge Test.
    • Chan. 2, 4, 7, 9 and 11 have high noise and the other 7 phonon channels have lower noise
    • in plot ''RMS of all Phonon Channels RMS'', noise varies periodically

  • Phonon :

    • channels respond different to same input signal setting, check this sheet for more details

    • input gain works at first, see plot 'Triggered Input Pulser'; but doesn't work later in plot 'Triggered Input Pulser All Channels'

    • in trigger test,

      • amplitudes of pulses not changed with different input gain setting
      • with Drv 0 and 1, ONLY Chan. 3, 6 and 10 triggered; larger amplitude in Chan. 10
      • position of pulses shift

  • Charge

    • Everything is fine, except the noise.

• RevE, SN_0, 2019.01.07

  • Noise :

    • charge channels, noise is flat at maximum
    • PSDs for only phonon channels
    • No Triggger Test

  • Phonon :

    • Checked Input Gain and Driver Gain. Both work

  • Charge

    • Something wrong in charge channels
