End of March, 2019-1

  1. [ ] Clean, reorganize AGG switch & patch panels, verify all port usage, move NAS to RGA1
  2. [ ] Test around Ru edge 22117
  3. [ ] Re-open plot window if closed curing a scan sequence
  4. [ ] dcm_pitch and rocking_curve() scan, C-c C-c & stop, how to kill motor?
  5. [ ] Mode f table hight
  6. [ ] fix toprj
  7. [ ] plot title, plot legends

Beginning of 2019-1

  1. [x] Refresh master log
  2. [x] Do-nothing SAF
  3. [ ] Better ways of determining Modes table
    • dm3 slits should be quite small ... 500 microns or so
    • make sure that beam comes out the center of the flange -- this will be needed for feedback detector
    • need slits of some sort on XAS table, certainly on sample stage, also at end of table.
    • improve trig in move_m2()
  4. [ ] Make a table/plot of flux on I0 as a function of energy with N2 in ion chamber
  5. [ ] Mode B, M2 hight
  6. [ ] Adjust pitch of m1, test resolution/calibration with narrow slits
  7. [ ] verify/update table height / beam v. ion chambers for the modes
  8. [x] Ti edge of BTOF, maybe some Ti standards

December Shutdown

  1. [x] Backup MC0X configurations to github
  2. [ ] Set dm3_bct to autokill after movement
  3. [ ] Are slits3 autokilling correctly?
  4. [ ] Even less noisy %xmode setting
  5. [ ] Rotation stage, continuous motion during scan.  Need to expose a velocity PV in the MC0[78] IOC.  Then ophyd can start and stop a velocity.
  6. [ ] Play with introspection: http://nsls-ii.github.io/bluesky/simulation.html
  7. [ ] Cryostat on ESR

Long term and lingering items

  1. [ ] compute reflectivity properties of current state of beamline mirrors
  2. [ ] Do a Mo/Mn harmonics test
  3. [ ] Stability above 20 keV, see Chris' Mo data similarity at high k
  4. [ ] can a pitch look-up table be made?
  5. [ ] Test energy calibration by measuring Cu (or whatever) and moving narrow slits vertically through beam
  6. [ ] Feedback!!!
  7. [ ] Does a big step really mean signal instability, see Jenny's Mn data pre-edge
  8. [ ] Commission single element Si-drift detector

Old list

  1. [ ] Speed and tuning of dcm-bragg and dcm-para.  Might be deadband of dcm-bragg....
  2. [ ] Some thought on a low energy flight path....
  3. [ ] continue conditioning the filters + decide what filters are needed for 311 crystals (or 111, for that matter)
