Pulse Selector in the Hutches

Friday Jul 5th

SOLVED:

  1. Fast OPEN and CLOSE
  2. :RESET_FLAG to monitor the finish reset process
  3. :AD (Align Done) PV Flag to monitor the pre-mode alignment feature

...

Tests all mode changes, and not found problems.
Ready to do a complete test on Monday.

Wednsday Jul 3rd

SOLVED:

  1. Integrate 4 shots instead of 3 (using ccdtake(3, 1 , bShutter=True)
  2. missing some shots when in 2 shots mode. SOLVED (USING MODE 3.2)
  3. Switch from mode anymode to anymode OK

...

  1. Fast OPEN and CLOSE
  2. RESET_PG Flag as PV (to monitor the finish reset process)
  3. ALIGN Flag as PV (monitor the pre-mode alignment feature)

Tuesday Jul 2nd

Initial XRay aligned positions:
Y position: 0.0000 mm
X position: 0.1512 mm

...

  1. Integrate 4 shots instead of 3 (using ccdtake(3, 1 , bShutter=True))  OK
  2. missing some shots when in 2 shots mode. SOLVED (USING MODE 3.2)
  3. Stopping the program (:RESET_PG 1) tooks long time than before 1-3 sec more)
    Needed one variable to check if RESET_PG is completed or if is OK to change mode.
  4. Switch from mode 1 to 3 still doesn't work. Example:
    ccdtake(1, 1 , bShutter=True) WORKS
  5. ccdtake(3, 1 , bShutter=True) FAILS!
    Still needs to do HOMING
  6. Fast OPEN and CLOSE doesn't work.

Monday Jul 1st

New tests with new ioc version (new MCode version)
Features:

...

  • Start position insensitive
  • HOME (Index Mark) position set to zero (DIAL)
  • START position (insensitive) relative to HOME (USER)
  • Record to report position (Encoder) as monitor at any time

TODO and issues in XCS

  1. NEXT: Uses First Trigger to Open, Second Trigger to Close
    The PP listen then for just one Event Code.
    Example of sequence:
    84 1 -> PP
    85 2 -> DAQ
    85 1 -> DAQ
    85 1 -> DAQ
    84 1 -> PP

' Program Fragment: MODE_1 (Single Shot)

  Mode 1.0 - Set GO to 1 to arm trigger. Single sweep from trigger.

Continuous Mode (MODE 2)
Code Block

' Program Fragment: MODE_2 (Continuous)

  Mode 2.0 - Immediately armed. Continuous sweep from trigger.

Burst Mode (MODE 3)
Code Block

' Program Fragment: MODE_3 (Burst mode)

  Before mode select, select sub-mode TG:
   Mode 3.1 - TG=0, Single Burst: Set GO to 1, then only single burst sequence will execute

   Mode 3.2 - TG=1, Continuous Burst: Execute burst sequence

   Mode 3.3 - TG=2, Open/Close Burst: Single pulse to open, single pulse to close

Setup Lab: EVR Settings

Setup Lab: Working with the EVR from pslogin
  1. in pslogin type (you need to have your securekeys):
    Code Block
     ssh ioc-tst-cam5 /reg/neh/home1/paiser/bin/evr.sh EVR=TST:CAM:05:EVR
  2. Then configure EVR as you need manually...
Setup Lab: In case the server ioc-tst-cam5 was power cycled
  1. Connect to the server:
    Code Block
     ssh ioc-tst-cam5
  2. Run the startup command that contains EVR ioc in:
    Code Block
     sudo /reg/d/iocCommon/sioc/ioc-tst-cam5/startup.cmd
  3. You should see with psproc:
