22 As defined in «DSS performance specifications» V.E at: Summary of the main functionalities (1/2) Mounted on the cryostat Connected to the slow control via Profibus-DP Connection to the ISEG HV module are: Vset (0 2.5V corresp. 0 5kV) Imon (current monitoring) (0 2.5V corresp. 0 10µA) Vmon (output voltage monitoring) (0 2.5V corresp. 0 5kV) The HV module has embedded HVmax, Imax, Tmax, RampUpmax, RampDownmax, ID number.

23 Hardware: : prototype boards n 2n 4 Profibus DP OUT CABSD100 BOARD 5 BSD OUT Profibus DP IN 1 AGILIPLUG (Profibus DP interface) Power supply 6.5V BSD IN or PT100 2 CMHV200 BOARD 3 ISEG

24 Difficulties to reach the specs due to ISEG module Difficulties to obtain technical informations from ISEG But we think the MHp has the following problems: Accuracy on current measurement not at the level of few na HV output not inhibited at start and stop Noise at 56.34kHz (chopping frequency) Short circuit protection not present

25 Current measurement: formula We tried to understand what it could correspond to: V Imon ISEG module 125kΩ Rimon Rmess IOUT DC/DC 500MΩ VOUT Rload V Vmon

26 Current measurement: formula If this is true, we should have: V V out out = = R R load mes I I out mes V Imon ISEG module Imon 125kΩ Rimon Imes Iout DC/DC 500MΩ Rmess Vout Rload I = I + mon out I mes V Vmon I out = V R I mon I mon V R out mes Very similar to: I µa V V = V OUT I MON Rmess out 8 If we plot this for various I out at different voltages : V I mon R = I mon I out + V R out mes

27 Current measurement: bench Power Supply 230V HV BOX Hardware: CMHV100/HV100 cards Software embedded : AGATA_DEV_2_0_ 6.5 V 300mA Serial cable Laptop with Acquisition Software Bench v Coaxial High voltage Cable (Draka htc ) PT100 cable Resistors Block Gauge High voltage resistor I load Multimeter 2001 KEITHLEY HV Module R load KEITHLEY 2001 Accuracy ±0.4nA R load 230V Grounding Grounding

28 Current readout vs. output high voltage Current Readout (ADC code decimal) Vimon = F(Iout) with Vout = Cst => 1kV => 5 kv step = 500 Volts 0 0,000 2,000 4,000 6,000 8,000 10,000 12,000 Current (µa) This shows the difficulties to calibrate one HV module

29 HV not inhibited at start and stop: measurements measurements State upon Power Up Power supply No more Vout~200V but dangerous for ADC (latch-up) 2 switches to be set to protect the ADCs VImon Current Readout is about 1V Vout State upon Power Down Power supply Current Readout is about 1,23 V VImon Vout Output CPLD

30 Measurement on voltage noise density: HV is set to 1kV Test bench layout: Oscilloscope Grounding 230V Serial cable HV module 6.5 V 300mA Power Supply 230V 230V Grounding Grounding Ouptut HV = 1000V Spectrum analyser 230V Vset at 0 V from 0Hz to 150kHz Grounding F chopping (ISEG)= 56,34kHz

31 What s next? Performances to be checked by GSI Different options: Everybody agrees with the ISEG module as it is The HV module should be defined again: Temporary solution for the first months of the demonstrator (with a CAEN crate for instance) The temporary solution becomes the final one. Difficulties to estimate schedule and costs
