ITk DCS
discuss ITk DCS
Attendees: Carlos, Josh, Luca, Diego, Samuel, Xola, Abdool, Simon, David, Alejando, Ioannis, Bongani, Gustavo, Gilles, Matt, Richard, Susanne, Stavros, Xola, Valentin
1. Testing in magnetic field (Diego Vera)
- Dedicated setup with one SCB amplifier on PCB
Field intensity 600 mT, three times the expected at PP2
Measure current and voltages in the amplifiers
No noticiable dedeviations observed
No ripples or spikes observed during magnetic ramp up/down
2. Temperature (David)
- Pending PP2 review actions
Testing over 100 m cable: done
Magnetic field testing of amplifiers: done
Check the op-amps are not Bi-CMOS: to be done
- Progress with influxDB
reading data from it
first interface to extract data
being designed fo the calibration of the sensors
- Dedicated presentation next week
3. Humidity
- Getting ready for second irradiation campaign
Required for PRR scheduled for week 21-25 October
2 FOS at 1.5 Mgy at irrad starting 9 of September
Analysis start earliest 9 October
Cleaning the code in the meantime
- Planning
Xola arrives September 1st
Doomnull will arrive September 5th
Bongani working on his visa hopefully before September 9
Abdool is applying for a longer visa
Simon Oct 14-18
- meeting with Sannio to discuss latest results
After the 20 of August
4. EMRB (Valentin)
- Extracted calibration constants from Voltage to Resistance of EMRB
- Modified PCB layout to improve powering of RPI
5. EMRH (Samuel)
- RPI hat with the same circuitry of the SCB
Including an ADS1115 ADC instead of the ELMB2 ADC
Four channels calibrated, three out of six gains can be used
OPC server in development to simplify usage
5. WinCC (Luca)
- Fully working prototype for all the signals in one ELMB
converts the ADC to temperature in the background
built into a library that can be run as a task by the control manager
