3 1. Analogue Front-End: Installation for testing purposes Location : SPS (BA50 / RA1705) SPS Schedule: Technical Stop 19/03/2015  Trip for Observation Technical Stop 08/04/2015  Analogue Front-End installation Technical Stop 26/09/2015  Digital Front-End installation ?? BE-BI-BL Jose Luis Sirvent Blasco 3 BWSD51731 Linear Wire Scanner S Start: m BWSRE51740: Rotative WS Prototype S Start: m 6.7m SLAC Collimator Potential location??

4 BE-BI-BL Jose Luis Sirvent Blasco 4 1. Analogue Front-End: The pCVD Front-End (BLM – Like): cables needed Power + 12V (BNC-CB50) Power - 12V (BNC-CB50) HG Signal (Type N - CK50) LG Signal (Type N - CK50) pCVD High Voltage (HVPF-CBH50) Pieces and Equipment provided by Ewald Effinger

5 BE-BI-BL Jose Luis Sirvent Blasco 5 1. Analogue Front-End: Are these cables on the BWSRE51740 location?? I’d say yes, and 5m seems enough to reach the potential location

6 Adaptation of: EDA HPA-High Frequency PMT Amplifier BoxEDA HPA-High Frequency PMT Amplifier Box By J. Koopman 08/10/2007 Used on BWS PMT as far as I know there have not been major issues with this amplif and radiation. BE-BI-BL Jose Luis Sirvent Blasco 6 2. The pCVD amplifier: A look in detail Input Protection Limited output voltage Stability and Low pass filter Relay for Test Lamp

7 Something extremely simple 1x THS3001 1x Resistor 1 K ohm 2x Resistor 51 ohm 2x Decoupling Caps 100nF 2x Decoupling Caps 1uF 2x SMA Connectors (In/Out) 2x LEMO Connectors (Power +/- 12V) Impedance matched In/Out Inverter configuration May be a good idea to use non-inverter configuration HG and LG channels with same polarity BE-BI-BL Jose Luis Sirvent Blasco 7 2. The pCVD amplifier: What is inside then?

8 BE-BI-BL Jose Luis Sirvent Blasco 8 2. The pCVD amplifier: What is inside then?

9 BE-BI-BL Jose Luis Sirvent Blasco 9 2. The pCVD amplifier: Some performance tests (1. Square wave 20Mhz) INPUT OUTPUT

10 BE-BI-BL Jose Luis Sirvent Blasco The pCVD amplifier: Some performance tests (2. Short Pulses 5ns width) INPUT OUTPUT

11 BE-BI-BL Jose Luis Sirvent Blasco The pCVD amplifier: Some performance tests (3. Charge Signal: AC coupled Square 10pF) INPUT OUTPUT Reflections due to decoupling cap (Impedance mismatching) Which are present also in the input: not amplifier’s fault

12 BE-BI-BL Jose Luis Sirvent Blasco Expected charge on pCVD for BWSRE51740 : Rough calculations based on A.Lecker simulations 2m from IP) # of interacting particles 2m (Gy) Charge in detector (C) Generated Current (A) Estimated signal magnitude 2m): *Roughly these values are divided by 5m

13 BE-BI-BL Jose Luis Sirvent Blasco Expected charge on pCVD for BWSRE51740 : Rough calculations based on A.Lecker simulations 2m from IP) # of interacting particles 2m (Gy) Charge in detector (C) Generated Current (A) Estimated signal magnitude 2m): *Roughly these values are divided by 5m To sum up with the analogue FE… Front-End construction Finished Amplifier characterization OK (minor modifications to do) Potential sensor location identified Cables availability guaranteed (but we’ve to take a look anyway) Cables length seems to be fine Signal amplitude estimated ( 50 – 100mV amplitude)

15 Link States: 1. Start-up at Test-Mode : Known pattern to check synch. 2. Latency calculation : FE loops data 3. Link on Normal mode 4. Remote QIE10 Initialization 5. Trigger signal for data acquisition 6. Data capture : Stored on BE SDRAM memory 7. Stop Acquisition 8. Post-mortem data transmission SDRAM  PC BE-BI-BL Jose Luis Sirvent Blasco Digital Front-End Status Status of the TO-DO list for complete system operation BE-BI-BL Jose Luis Sirvent Blasco 15

16 BE-BI-BL Jose Luis Sirvent Blasco Digital Front-End Status First QIE10 acquisitions with function generator

17 BE-BI-BL Jose Luis Sirvent Blasco Digital Front-End Status Preparing synchronous acquisitions The idea: To use a system CLK 40Mhz for Igloo2 REFCLK and to trigger F.Generator Pulses on synch with 40MHz System CLK propagated to FE Latency/Phase deterministic system Synchronous acquisitions on FE The objective: Test jitter performance Check TDC functionality Check ADC linearity System CLK Synchronous Pulses (Charge) Back-End TX CLK Front-End RX CLK
