ProtoDUNE - SP SLOW CONTROLS MEETING 11/11/2016 CERN – EP/DT Giovanna Lehmann – Xavier Pons CERN – EP/DT

Slow control priorities To define the rack allocation, space needed by equipment and power consumption. “Clients” should send the request of the space needed in 19’ rack in terms of U units. Power supply configuration? Crates number? To define the quantity of SC racks needed. To design the rack electrical power supply distribution

1. Heinzinger 300 kV power supply 1.1 Model, type? (Is the PNC or PNChp-Series?) http://www.heinzinger.com/uploads/files/downloads/PNChp.pdf 1.2 Slow control connection to analogue interface 15-pin sub-d connector for PS signal monitoring and control. Option 10 recommended

1. Heinzinger 300 kV power supply 1.3 There is the option (72&76) of RS-232 communication for parameters monitoring. WA105 tried with not a good results. 1.4 Interlock according LAr levels. Is the HV power supply equipped with interlock circuit? Then the power supply should be ordered with the options 02&52 Otherwise SC should think a circuit to interlock the HV power supply?

More information is needed to integrate this system in the SC. 2. CORONA MONITOR 2.1 Custom built. 2.2 System monitor. 2 monitors signals (?) on each filter to determine breakdown. 2.2 Calibration Signal. 2 pulsed signals ( 1per monitor) (SMA connector ) More information is needed to integrate this system in the SC. Specifications of the signals? …. and process?

3. MPOD Crate 3.1 MPOD Crate configuration needed. Which type of PS slot used in the crate? 3.2 How many crates? Important, for booking rack place, allocation,… 3.3 Important all the MPOD crates should come by default with the option Ethernet interface for connecting them the SC trough Wiener OPC server. In contact with CERN WinCC support for integrating them in the SC. 3.4 APA WIB voltage current monitoring and control by means of the MPOD?

4. PD calibration and cabling 4.1 MPOD crate used? If yes, the crate configuration needed, which type PS modules? 4.2 Voltage for current regulation of the UV LEDS needed? If yes, more details are required of this system

5. Outer Veto 5.1 This detector will be on building ground: - Not included into detector racks foreseen so far - Will need to find emplacement + detail on SC 5.2 CAEN power supply supported by SC. Configuration required, PS module type 5.3 LV Agilent N6700, possible to replace by Wiener and integrate it in a MPOD. Only 6 channels 5.4 ??? * remotely controlled power strip: computers, NIM crates, etc * 2-3 computers for DAQ and event builder * monitor temperature in rack and computers

6. Ground planes 6.1 ‘ The impedance monitor has network capability into slow controls system’. More details of the system or device are required ?

6. Beam Plug 6.1 For the moment we can assume the following: * Two pressure sensors * One temperature monitor * One flow rate monitor * Two remote control valves Control N2 supply line, safety interlock… If possible more details of the used hardware: valves, sensors …

7. Purity Monitors - TPC 7.1 Install 4 purity monitors. 2 channel readout to LabVIEW algorithm in a DAQ PC for purity data. Is it possible to integrate the LabVIEW algorithm into SC directly? 7.2 Control LV/HV through SC. To check if the BERTAN PS can be integrated in the SC. We recommend to use the Wiener PS in order to standardize the equipment

8. Purity Monitors 8.1 Light source automatic ON/OFF for gold photocathode done by SC? 8.2 If LED lamps used, control by SC of the signal sent to LED controller. 8.3 To check if BK-PRECISION PS can be integrated into the SC. We recommend the use of Wiener PS. 8.4 More details are required.

9. Cryogenics 9.1 How to exchange data between cryo and SC? At the low level = hardware signals, high level in the scada ? 9.2 List of signals to be exchanged. List of signals owned by SC? 9.3 Flor’s list. This hardware belongs to SC or to the Cryo? 9.4 More details are required. 9.5 As the Cryo experts are at CERN, we’ll contact them to clarify this point.

10. Level meters & pressure sensors 10.1 Sensors and signal type? Signal amount? 10.2 Level meter interlocks the Heizinger HV power supply 10.3 More details are required

11. Temperature gradient monitor other temperature sensors 11.1 Read-out type of the 25 PT100 sensors? Can PT100 & PT1000 be read directly in the SC?

12. Cameras and lighting 12.1 What and how to integrate into SC? 12.2 More details are required
