Checking Transmission, Alignment, and Beam Energy

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:

1. Make sure there is no gas in the target
2. 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)
3. run the XA_transmission.rossum script either by typing in the command line
   • ./startTransmission.sh ... or...
   • ???
4. A window will pop up, click start tasks then let rossum do its thing
5. when it is done click exit and rossum will spit out numbers
6. Record transmission percentage and uncertainty

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