PANDA Collaboration Meeting Amplitude linearity test of LNP Preamplifier December 2012 I.Keshelashvili, W.Erni, M.Steinacher Group of B.Krusche University of Basel
Introduction ● Amplitude Linearity ● Double-burst Linearity ● 'Mass production' test ● Conclusion
Why Amplitude Linearity ? Calibration Parameter Linear? ∆ E N γ p.e. Q D V LNP PWO II VPTT Shp SADC
Amplitude Linearity: Method A(1+2) A(1) A(2) A(1)+A(2) A(1+2)
Amplitude Linearity BLUE LED LED 1 Driver Amp 2.5-7V 12bit DAC SPI DAC 0-3.3V RS232
Amplitude Linearity: samples VS events
Amplitude Linearity: example
Amplitude Linearity: VPTT LNP & VPTT LNP Maximum output V
Amplitude Linearity: VPTT + Shaper Basel Preamp Linear Device
VPTT & LNP Double-burst Linearity Basel LNP-PreAmp + Hamamatsu VPT HV: 704V Interval 500us 500ns - 10us 2MHz - 100kHz
VPTT & LNP Double-burst Linearity
VPTT & LNP Double-burst Linearity
Mass Production LINUX DAQ Control RS232 FPGA HV (900V) Power VME LED Driver I (nA) Consumption SADC LNP Test Box
'Mass production' test ● Amp,Freq Linearity ● Gain ● HV ● Power Consumption ● 10'000 until 2015 ● All data in MySQL database
