Dragon shift tutorial notes - look around Smaug for documentation (posted on the wall) on crashing systems & Don’t Panic

'''Every hour you should check the gas target pressure/temperature and the beam intensity on FC4 And the more detail you put into the midas elog the better!!'''

Note: if the dragon experts are busy tuning or doing other things if someone could make sure that all gets documented that would be amazing!!

'''Beam Intensity and Gas Pressure:'''

- If the current drops below the minimum beam intensity for the experiment during a rossum cup reading of FC4 call ops and kindly request that they work on it. Also call them if you see Large fluctuations which indicate unstable beam. Then notify dragon expert.

- For gas target issues/ if it needs to be topped up, contact a DRAGON expert.

- Target temperature: ~35.9 °C. If spiking, check LN2 cooling; reset in EPICS vacuum system if needed.

'''Terminal Usage:'''

- New terminal logs into Daenerys. You will need to ssh into Smaug: ''ssh -Y smaug''

- If the DAQ crashes, in any directory on Smaug run `''start_daq.sh''` to restart the DAQ. You will then need to also restart Rossum.

- If RootBeer is empty/gone, then the DAQ has crashed.

'''RootBeer:'''

If this crashes…

- On Smaug, run `rbdragon`.

- Load histograms -> select setup and consult a DRAGON expert or the TRIUMF ELOG for correct plots.

- Double-click plots to open. To open multiple, click "Create New" first.

- Click "Start Refresh" and "Attach Online" – updates every few seconds with online data.

'''MIDAS'''

- Open Chrome in a new window, if not already open – all the bookmarks at the top are important/useful

- MIDAS status lets you know how the run is going.

- If you need to change anything, document this in the MIDAS elog (found on the sidebar of the webpage):

· If there is a drop in beam intensity, gas pressure change, etc., make a log.

· '''Ideal time for beam operators to take a snapshot of their setup is in between runs or mid-run. Then make an elog that ops took a snapshot.'''

· If alarms go off, go to the alarms sidebar in MIDAS. If any are red, call a DRAGON expert.

'''Starting a New Run:'''

ONLY START A NEW RUN WITH ROSSUM!!!! (START TASKS START SCHEUDLE)

- Transition page: ensure all status bars are green and connected.

- If one is red, the connection failed. Go to programs on side bar and hit start.

- Status page: provides run info.

'''Rossum:'''

- Script for autostarting runs every hour.

- Used for checking transmission – should be done at the start of every run.

- Check values for Faraday cups upstream/downstream of the target.

- Restart Rossum if the DAQ crashes:

- `./startRossum.sh` to restart Rossum

- Start tasks, then start schedule.

- If auto-start fails, start a run first, then repeat the steps. If that fails call a dragon expert.

-If you need to stop the autopilot hit start tasks then stop schedule that way there are cup readings at the end

-START AND STOP '''TASKS''' IS ONLY FOR THE '''FARADAY CUPS'''

-START AND STOP '''SCHEDULE''' IS ONLY FOR '''STARTING AND STOPPING MIDAS RUNS'''

-once you hit start tasks do not touch anything else while rossum is taking the cup readings... it will crash otherwise

'''If Things Go Wrong:'''

- PUT THE FARADAY CUPS IN (labeled FC*** in optics section of EPICS).

- Call ops to insert FC4, or use `fc4in.sh` on Smaug to insert (and `fc4out.sh` to remove).

- Green = in, Grey = out.

'''Additional Notes:'''

- Main ISAC control has links to optics, vacuum system pages.

- If you need to start a run first then start Rossum, ENSURE YOU SELECT "WRITE DATA" when restarting the run.

- To add something to striptools, middle-click the parameter, drag it to striptool commands.

Checking Transmission, Alignment, and Beam Energy

2025-07-02T23:51:42Z

Mallory Loria:

When the operators are done tuning the beam to DRAGON the first step is always checking the transmission, beam energy and alignment.

If everything looks good then record the valuse for transmission, alignment (whether it is good or not), and beam energy (as well as how you calculated beam energy) in the MIDAS ELOG.

'''Checking Transmission:'''

# Make sure there is no gas in the target
# Check that all faraday cups are in (MCP's out, charge and mass slits open, profile monitor is not in, and all necessary valves open)
# run the XA_transmission.rossum script either by typing in the command line
#* ./startTransmission.sh ... or...
#* ???
# A window will pop up, click start tasks then let rossum do its thing
# when it is done click exit and rossum will spit out numbers
# Record transmission percentage and uncertainty
# Dragon does not accept less than 90% transmission (generally as a rule of thumb. special cases may apply)

Now to check the energy you can either do so with gas in the target or with out. To determine have epics open and go to ''Optics'' then open the ''new scaling page. -->'' Eeter the mass and charge state of the beam as well as the beam energy (??) hit enter (DO NOT HIT APPLY TUNE yet). --> look at the NMR1 value --> If it is less than '''5950 G''' you can bend it without gas --> if it is greater than that you need gas to bend it

'''Checking the energy in (no gas in the target: NMR1 < 5950 G):'''

# Put FC1 in
# close charge slits to 2 mm
# go to new scaling page (check that charge state, mass, energy are correct) hit enter NOW HIT APPLY TUNE
# Pull out FC1 (again making sure cups are in everywhere else)
# check if beam is centered in the charge slits
# adjust Energy on scaling page until beam is centered
#* if you cant see beam for whatever reason check the alignment on the profile monitor
# [[File:Energy check calculation.png|thumb|204x204px]]Once beam is centered RECORD NMR1 value and calculate beam energy using the formula. Where B is the NMR1 vlaue in Gauss, q is the charge state, m is the mass (preferably use the exact mass in AMU)

If energy looks good (usually within 5 keV/u of what we asked for form ops) doccument energy and open charge slits again.

'''Checking the alignment:'''

# Put FC1 in
# Put the profile monitor in
# take FC1 out see how beam looks (left figure is the x and right is the y) --> you may need to adjust the gain scale to see the peak clearly
# turn the quads off (Q1 and Q2) and see how much the peak of the centroid moves. If the alignment is good then the peak will not move more than 1.5 of the green wires. If the peak moves more than 1.5 of the green wires alignment is bad.

If transmission, alignment, and energy look good then you are good to continue tuning through dragon (make sure to call ops and tell them things look good and thank them!)

If any one of these looks bad the beam needs to be given back to ops and reworked. (usually changing alignment messes with transmission so it is tricky)

This is an itereative process usually but again dragon needs all 3 to be good before continuing

# Dragon does not accept less than 90% transmission (generally as a rule of thumb. special cases may apply)

Now to check the energy you can either do so with gas in the target or with out. To determine have epics open and go to ''Optics'' then open the ''new scaling page. -->'' Eneter the mass and charge state of the beam as well as the beam energy (??) hit enter (DO NOT HIT APPLY TUNE yet). --> look at the NMR1 value --> If it is less than '''5950 G''' you can bend it without gas --> if it is greater than that you need gas to bend it

'''Checking the energy in (no gas in the target: NMR1 < 5950 G):'''

# Put FC1 in
# close charge slits to 2 mm
# go to new scaling page (check that charge state, mass, energy are correct) hit enter NOW HIT APPLY TUNE
# Pull out FC1 (again making sure cups are in everywhere else)
# check if beam is centered in the charge slits
# adjust Energy on scaling page until beam is centered
#* if you cant see beam for whatever reason check the alignment on the profile monitor
# [[File:Energy check calculation.png|thumb|204x204px]]Once beam is centered RECORD NMR1 value and calculate beam energy using the formula. Where B is the NMR1 vlaue in Gauss, q is the charge state, m is the mass (preferably use the exact mass in AMU)

If energy looks good (usually within 5 keV/u of what we asked for form ops) doccument energy and open charge slits again.

'''Checking the alignment:'''

# Put FC1 in
# Put the profile monitor in
# take FC1 out see how beam looks (left figure is the x and right is the y) --> you may need to adjust the gain scale to see the peak clearly
# turn the quads off (Q1 and Q2) and see how much the peak of the centroid moves. If the alignment is good then the peak will not move more than 1.5 of the green wires. If the peak moves more than 1.5 of the green wires alignment is bad.

If transmission, alignment, and energy look good then you are good to continue tuning through dragon (make sure to call ops and tell them things look good and thank them!)

If any one of these looks bad the beam needs to be given back to ops and reworked. (usually changing alignment messes with transmission so it is tricky)

This is an itereative process usually but again dragon needs all 3 to be good before continuing
