Present:
Commenced: 10:00am
Adjourned:

==MPS Status==
*Argon only turned on during force tests
*Detectors in working order

==BLM force tests==
*Straight forward so far
*Prevention of second force
*if applying second force, instead of rejecting it, it removes force from first detector and forces the other
*EHAT:LIC1 (has 2 sets of redundancies)
*EHAT:LIC2 ()
*Done half of the BLMs without beam
*And then do the beam tests
*ELBT wouldn't include any force parts
*April 22nd was the plan for beam back, but need to get egun oil
*April 22nd shielding should be replaced that day

*Collimator in the making (in one of the machine shops)
*Designed by sci-tec
*No installation before summer
*Need specs from Stephanie
*Need work request for the install, so likely needed since multiple groups will be involved
*

==Collimator in front of dump==
*Has been installed by Doug
*Next steps?
*Do we have specs, to check if it can be implemented into our MPS system? ==> Stephanie

==Fibre/Simulations==
*No updates from Alexey
*Has working simulation and now just doing checking of various positioning of detectors
*Put LICs along the beamline in simulation, will determine on how many we need
*Timeline for when the beamlines will be in place?
*Will beamlines be installed both at the same time? Probably?
*Need to have large benders from BL4N installed first
*

==AOB==
*Darklight got RTI around 400k
*And already have an NSERC
*Build a ring in the ehall to boost the energy
*On top of being committed to realize terraherzt
*And need protection system for the ring as well (for free! ;))
*Some old PhD thesis for design draft available and from ERL (Berlin)
*Fibre for the ring? As MPS option. Cherenkov based.

MPS meeting minutes – Feb. 8th, 2024 – 10am online
Present: AL (chair, recorder), SR, BH, MA, KL, BH, HH, TP, RC, MR
Commenced: 10:00 am
Adjourned: 10:35 am

==1) Status ==
*E-hall is open today.
*Emergency opening on Monday. Turbine issues.
*Warm oil tank.
*One of the insulators cracked. Keep running, but need to monitor tank.
*Following up on reason for EGUN:BIAS trip due to a stage 2 trip from EABT:LIC3B. This was due to losses from EACA. Caused a dozen trips towards end of the test. But detector worked as it was supposed to.
*Observed spikes in charge reading of EABD:PMT0. Irregular. Noise pick up? Not dramatic, but noticeable regular spikes. May hint at developing problem.
*Before end of 2023 year, there was an issue with EMBD:LIC2 (Sudden trips). Did problem come back during the last months? Brandon and AL checked connections, couldn’t find any visible problem. ==> No re-occurrence since last year.
*How long will shut down be?
*When is Darklight going in/out?
*Expect differences with coverage when Darklight goes in
*EHD line after EHDT:MB4 to the dump will be completely changed. One mode with darklight target out and one mode with darklight target in.
*Darklight will need 10kW. Will it be heavily shielded?
*Collimator will be installed in front of the dump.
*BPMs are getting moved. Not used in the same way.
*Who shuts down beam when collimator sees to much
*Need similar channel. Target this in the upcoming shutdown. Modification to the daughter board. Solder 2 capacitors. And
*Document to share the specs. An order of magnitude of power. Need specs from Stephanie. No CW, just pulsed.
*Verify connections before shielding goes back.
*Commissioning for beamloss monitors done
*Run to EMBD. HV pick-up. Expect to be contacted. Number for LIC defeat in FLASH report.
*6-8 weeks shut down. Doug needs to install collimator behind the dogleg. Takes until April

== 2) Interlock functionality testing ==
*Any time for this?
*3 BLM force functions have been completed
*Do the rest during shut-down.
*Mike fixed that one LED wasn’t lighting up.
*Still inconsistencies in messaging, but otherwise functioning nicely

== 3) Simulations ==
*Progress from Alexey
*Need to benchmark simulations with what we see in the e-hall.
*Could use old scans/spills
*If required, do this before the BL4N collimator shut-down

== 4) Fibre ==
* No update.

== 5) AOB ==
*Ricky is working on license enforcement system related to EOCEM replacement. Started looking at logic and planning to do the testing during the shutdown.

*Calibration document
*Planning for BL4N. We have 5 FSD modules. Need 2 for the other side of the tunnel
*BLM modules (3 are in use)
*Run fibre from 1 FSD to the other FSD

== 6) Action Items ==
*AL to submit calibration document.
*SR to send specs for collimator. Needed for integration into FSD shutdown.

2023-03-02T19:13:21Z

Lennarz:

Present: BH, MA, RC, SR, MR, HH, RN, AL
Commenced: 10:01am
Adjourned: 10:30am

==BLM force functionality==
*Roll-out done by Mike this week.
*First test performed with Brandon. Forced one detector, and it was still possible to send beam
*First tests successful
*AL verified threshold and voltage settings are correct after roll-out
*For EMBD:LIC2 (on the detector page), the slider for HV is at zero, while the voltage seems on and the readback is at 500V. MR to look into this.
*Next step: Testing. AL to write up testing/commissioning procedure. This has priority.

==E-linac Status==
*Obtaining license will still take at least 6 weeks.

==BLM position==
*AL messaged Darren Blom to get remaining BLMs fixed in place
*Will pick a day when hall is open next week
*Darren suggested 3D printed option for mount of one of the low-energy detectors that was moved during work last year
*Even though darklight will be installed in high energy dump section, LICs should be fixed in place for now.
*Recommissioning will be required whenever changes to beamline are made

==Post Mortem==
*AL to do tests with RC next week to check functionality and readout
*Use LEDs and external trip for offline testing

==Fibre==
*No update

==BLM calibration==
*BLM calibration functionality will be implemented once BLM force functionality has been tested
*AL to finish document first

==AOB==
*ELBD:PMT0 detector should no longer cause a trip of the FSD, as it's not positioned along beamline anymore, but in front of egun window for monitoring
*MR to remove this detector from trip logic and detector ok check. Will require work permit and update of documentation

MPS meeting minutes – June 16th – 2022

Present:HH, RC, KL, AD, AL, MR, MA, SR, BH
Meeting commenced: 10am PT

Meeting adjourned: 10:30am PT

===MPS status===
*LIC0 trouble shooting
**EMBD:LIC0 indicated red on "installed" status. Maybe module wasn't seated properly?
**HH investigated this morning
**It's fixed but unclear how this happened. Maybe during FLASH update
**In the future verify epics status for each channel after completing work
*The beam path restrictions are not really set up to make sure BLMs are running. Only checking HV for low-energy section
*Can we implement this now for the medium and high-energy sections? Would this cause issues, when temporarily disabling detectors?
**Check seated status, Argon, HV, PMT current readback
**Similar to optics ok, given set of detectors to be turned on. Maybe modification of the run permit
**Work request
**Amend document for seated status
**Calibrations
*Argon flow started yesterday
*Keiko updated signal PV in the alarm handler and archiver for former ELBT:PMT1A now ELBT:LICSP1 (spare channel)

===S1 to S2 delay===
*the delay between stage 1 trip detection to stage 2 trip has been implemented by HH
*detect mode was fixed at 10us (plus some inherent delay through the FSD and timing system ~5us).
*Delay is adjustable between 1us and 25us. Default is 10us.
*Look for S2 trips. Log how many we get.
*Brandon just started tuning and inserting view screen tripped PMT1B causing S2 trip. Dark current much higher than before shutdown?
*EPICS indications for S1/S2 trips => Ricky to check what is indicated when to avoid confusion on trip vs stage status.

===FLASH===
*Board modifications complete
*HH thinks the modified board will work for FLASH. Before it can be install, Controls will need to change the conversion factors on
the EPICS screen. Basically all existing conversion need to be increased by 100.
*HH updated user manual.
*Ricky to '''update the conversion factors.'''
*FLASH to run next week
*MA: Has the new FLASH board (Reads 920 nA.) been tested with a current source? HH checked in the lab.
*Nothing was changed in the hall
*HH: Old board can be put back easily if needed.

===AOB===
*Check if we can use EACA conditioning to test fibre. Check if yanyun is doing pulsed conditioning or cw.

===Action Items===
*AL: Addendum to BLM controls configuration specs document (Document-193864). Add "installed" status.
*AL: submit work request to implement add BLM settings/status to beam path restrictions
*RC: Update conversion factors for FLASH channel
*AL: Finish calibration documents
*RC: Verify displays of S1/S2 are correct
