  This is a summary of the ID14-4 operation for users.
  Click on the links for further information.

  Your local contact: Between 8am and 10pm, but not on-site at all times!
  Floor coordinator: 25-25 (between 10pm and 8am)
  CC4: 23-22

  1. Beam Line Manual

These pages contain information for beam line computers, data collection start, data processing, trouble shooting, backstop alignment etc for ID14-4


  2. Safety Training

Located in PluoH, room 203.


  3. Passwords and Door Codes

Only available on intranet site (see below)

 

  4. Hutch EH4 (downstairs)

  • Beam size/Rotation axis marked in MxCuBE screen on artemis2 (control cabin) and weka (EH4).
  • Align Crystal: Use the 3-click centering in MxCuBE hutch tab.
  • Search hutch: one button inside the hutch on the wall nearest ID14-EH3.
  • pin length - see mini-diffractometer page for more details. A sample changer will be installed sometime next year and we recommend people to start standardising their pins to help the smooth transfer to our sample changer. More details can be found on our sample changer webpage


5. Control cabin CC4 (upstairs)

  • Beam Line Computers
    • artemis2: Experiment control (Exes) 
    • britt: Data processing
    • pc144cuda: data processing terminal and hutch display screen.
    • wid144io: windows PC for data backup - no external access.
    • leda (windows)/carme (linux): same screen, use Scroll-Lock (x2) to switch
    • Printer: located beside pc144cuda
  • Data Collection Software: mxCuBE runs on artemis2, click on icon to launch it: In case of problems, ensure the ''EXP'' (EH4 on lid144) spec session is running. This program controls goniometer, detector, monochromator and runs data collection.
    • Typical exposure : 0.2-1 sec per deg for E=12.6-13.2 keV
      With 0.2s exposures, expect to collect between 20 to 30 images per minute; always be aware of radiation damage (>1 sec/deg)
    • As you like, normally we use 1.
      Use more than 1 pass for >10s exposure time
      (Recommend data collection speed for the phi spindle: max = 2 deg/sec ; min = 1 deg/10sec.)
    • Beam size: (25 to 200mm but beam cut by slits). Nominal size is 100mm x 100mm.
    • Distances Crystal to detector allowed:
      Min Dist = 110mm, max 700mm

Data written on NICE storage disk. Create your directories from mxCuBE interface

  • Front end control and machine status
    On artemis, there is a Front End desktop where the front end application should be running. If not, then click on "Front End application". Otherwise, open a terminal window in this desktop and type:

    xhost +
    rlogin deino
    setenv DISPLAY artemis2:0.0
    idappli_appli

    Status of machine with messages from machine group (beeps for a new message)
    Automatic mode [Commands/Remove or Commands/Set Automatic mode]
    This mode is set only for 16 hours. Think of resetting it sometimes. Check of the undulators' gaps [Commands/ID control]. The maximum intensity of ID14-4 is at 13.2keV. For this the U35 should be at 16.3, the U23 should always be at 16.01 and is never moved and the U24.4 is set to 19.6 mm. See the Edge Table web page for the undulator positions of other elements. Always inform the users of the other side stations first before changing the undulators, since this might effect their intensity.

  • Image viewing
    Images can be viewed on artemis2 by clicking on the Start "Detector Follow images" icon. If ADSC image viewing software hangs on artemis2, then at any point you can restart it by clicking on  Start "Detector Follow images" icon. You can also launch adxv viewing software on carme by typing ‘adxv image_name’.

  • Optimise beam intensity
    From mxCuBE: Quick Realign button 
    If there are not enough counts because you e.g. have just moved to an exotic energy.

  • Processing your data on britt (from pc144cuda or carme)
    A template files for XDS and mosflm are automatically created with up to date beam parameters. Thses are stored in a 'processing' subdirectory of the data directory created by mxCuBE.
    Wavelength is variable. You normally find the distance, x- and y-beam positions in the image header.
    ADSC Q315r detector: 315mm X 315mm (pixel size = 0.1026mm in Hardware Binned mode)
    For denzo the image format is ccd adsc unsupported-q315 binned.
    Mosflm requires only the keyword scanner adsc to match the ADSC Q315r detector
    Strategy needs the keyword format Q315BIN

  • Data Backup
    A special windows PC (wid144io) has been installed for backing up your data on external USB disks.

  • Trouble shooting
    Under the web sections Trouble Shooting or Align Backstop for the alignment of the beamstop.
