titlePulse Picker TODO List

Pulse Selector in the Hutches

Table of Contents

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

IMPROVED:

  1. PV's for OPEN and CLOSE range check
  2. New class to provide EVR default settings (used inside Princetion script)
    No need anymore python Picker script to set EVR.

TODO (lower priority):

  1. Provide a XCS_Python home function on command line.

ISSUES:
When IOC reboot the Pulse needed to be Homed again.
We will investigate more on Monday.

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

IMPROVED:

  1. PV's for OPEN and CLOSE range check
  2. Pre-mode alignment subroutine.

TODO:

  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

Test examples
Single shot 10 images

Code Block

   ccdtake(1,10, bShutter=True)

Burst mode 3 shots 100 images

Code Block

   ccdtake(3,100, bShutter=True)

Alignment Laser used to test the system

  1. To insert the laser
    Code Block
    
    In [2]: rl2.movein()
  2. To remove the laser
    Code Block
    
    In [2]: rl2.moveiout()

Results: Tests doesn't work satisfactory. Problems found in Mcode:

  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:

  • New MODE (MODE 3.3)
    • One EVR Trigger OPEN, Next EVR Trigger CLOSE OK IT WORKS
  • Fast OPEN and CLOSE commands NEED TO BE TESTED

TO BE IMPLEMENTED IN THE MCODE ASAP:

  • 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

==================================================

in xcs-control:

caput XCS:SB2:MMS:09:SET_VE 0

modify reg/d/iocCommon/sioc/ioc-xcs-trigger-ims/startup.cmd

to point to working area,

ssh ioc-xcs-mot1

kill ioc (telnet localhost...)

boot ioc from reg/d/iocCommon/sioc/ioc-xcs-trigger-ims/startup.cmd

===================================================
to fast open/close:
caput XCS:SB2:MMS:09:MODE_OPEN 1 (C2 should be around 655)
caget XCS:SB2:MMS:09:SE_L (to be read 4)
caput XCS:SB2:MMS:09:MODE_CLOSE 1 (C2 should be around 0 or 2x655)
caget XCS:SB2:MMS:09:SE_L (to be read 5)
===================================================

   1. START STOP mode3.3

         SET_TG 2

         SET_MODE 3

  2. FAST OPEN/CLOSE PV

  3. START POSITION INDEPENDENT:

  1. ISSUE: No counting -> trigger "burst stop" sometimes
  2. FIXME: Avoid arm/disarm
  3. TODO: Benchmark time needed for position correction
  4. FIXME: Start position dependent on present position
  5. TODO: If
    position correction takes <= 10ms the do each time
  6. TODO: Home offset as PV
  7. TODO: Make Aperture Angle as VAR and PV (to be changed as needed)
  8. TODO: Dial zero @ Encoder Home marker
    User zero @ "Aligned" position (means that RESET_PG reset only users) - to be discussed with Jeff
  9. TODO: Fast Open/Close PV
  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

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

Mode Descriptions

Mode 1: Single pulse
Mode 2: Continuous trigger

Mode 1 and 2 should be the same program, as the Seq will generate the pulses to the motor, and open/close operation shouldn't make any difference whether it is 1 or more. The motor sees a trigger and moves.

This mode is accessed by <PV>:RUN_MODE2

Mode 3: The motor opens on a pulse, counts N pulses and closes on the Nth pulse. The pre-trigger and close trigger should be factored in by the upper layer software to determine the proper N value to put into the motor. All the motor does is, open on N=1, count, then close on N=N.

This mode is accessed by <PV>:RUN_MODE3

Mode 1 was programmed like just mode 2 with a User "Trigger" enable/disable, which may or may not be useful for us. Sort of like 2 layers of enabling, versus just 1 for mode2
This mode is accessed by <PV>:RUN_MODE1

Reset Modes to start new mode:
<PV>:RESET

Motor Interlock Scheme

Screenshots

Pulse Selector Test/Checkout Procedure (6/10/2013)

X motor calibration

  • Found offset from X zero position: 5.8075 mm from + limit
  • Offset for X zero position: 5.7332 mm from - limit
  • Limits performed as expected, and in place before hardstops

Y motor calibration

  • Offset from +Y limit to zero: 15.6689 mm
  • Offset from -Y limit to zero: 7.9956 mm
  • Limits performed as expected, and in place before hardstops

New Interlock:

Add Y motor interlock, position >= 2 mm above 0 position, no X movement allowed

X-Y interlock stopped working today, need to investigate.
