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

Safety training must be completed before starting experiment.

3. Passwords and Door Codes

Only available on intranet site (see below)

4. Hutch EH4 (downstairs)

Beam size/Rotation axis marked in MxCuBE Hutch tab on artemis2 (control cabin) and weka (EH4)
Align Crystal:
Search Hutch: one button inside the hutch
pin length - Spine standard pins (22 mm) only please, we do not guarantee other types will work. An SC3 sample changer is installed and more details can be found on our sample changer webpage

5. Control cabin CC4 (upstairs)

Beam Line Computers
- artemis2: Experiment control (MxCuBE)
- mx144: Data processing
- carme, pc144cuda: data processing terminals
- wid144io: data backup
- printer: a4bid144
Data Collection Software mxCuBE, click on "Start Data Collection GUI" on artemis2 to launch it: In case of problems, ensure the ''EXP'' (EH4) spec session is running. This program controls goniometer, detector, monochromator and runs data collection.
- Typical exposure : 1 sec per deg for E=12.6-13.2 keV
  With 1s exposures, expect to collect between 30 images per minute; always be aware of radiation damage
- Number of passes: as you like, normillay we now use 1.
  Use more than 100ms exposure time
- Slit sizes (25 to 200mm but beam cut by slits); for smaller, ask the local contact. 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 Exes_ProDC interface to avoid permission problems

N2 level for cryostream
Right panel in MxCuBE should contain all info concerning cryostream status
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 U42 should be at 17.08, 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 by typing ‘adxv image_name’.
Distance of detector / Resolution at border?
Use Bragg's law, your student, or the adxv program with settings option.
Optimise beam intensity
From Exes: Quick Realign button
If there are not enough counts because you e.g. have just moved to an exotic energy, one can use from Exes: Commands/Realign which is similar like Quick Realign but uses wider ranges and longer exposure times.
Processing your data on coral (from pc144data or carme)
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. See Data Processing on the web for input files and advice.
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
USB2 ports are available on pc144data (prefered backup machine) and carme (use the hubs on the table). For DVDs, please find more instructions for burning a DVDs etc on our backup pages. Send an e-mail to us if you feel that other kind of backup systems are required.
Trouble shooting
Under the web sections Trouble Shooting or Align Backstop for the alignment of the beamstop.
