X12-C

Hutch	Detector - ADSC Quantum 210 Diffractometer - Crystal Logic One should always check the vertical and horizontal cross-wires while starting a new group. If communication with the diffractometer's motors is lost for some reason, one has to turn the power off in the controller inside the hutch (the switch is right on top of the vacuum pu mp), and then turn it back again. The next step is to restart the Crystal Logic program on the PC. However, unlike, X25, there is no home switch in CBASS at present, hence one must HOME distance, vertical, and omega motors ONE AT A TIME. When the program is started, the z-translation for the goniometer is not enabled; it must be opened with an icon in that area. At present the best way to position the crystal in the beam is to rotate the crystal using the omega axis, shift from the camera plane to the XYZ plane and adjust x-translation when omega is 0 deg or 180 deg, and y-translation when omega is at 90 or 270. If you are moving the axes using the + and - icons, the axes need not be exactly positioned at these angles, but may be within 5 degrees of the numbers given above.

Hutch	Detector - ADSC Quantum 4 Diffractometer - Nonius Collection is stuck on 'Readout' or 'Dark' Lost communications with Detector Computer. Abort collection. Close Cbass. Go to Detector Computer rack and restart 'Quantum Console' software. Restart Cbass. Goniometer is stuck at limits and not moving Last resort to move a stuck motor using the nonius control pad Press 'Left' arrow or 'Right' arrow (sets direction). Press '9' (sets speed). Press 'Move'. Press axis to rotate about (kappa, omega, phi). Keep your finger on 'Clear' button to stop motor motion. Moving omega, kappa or phi manually If the goniometer runs into a soft limit or bangs into the collimator, you may need to manually move the motors back to their zero positions. For omega, you need to remove the case behind the arm holding the detector. You will see two little gold gears, turning the outer one will move omega. For kappa, you need to remove the see-thru black/grey case covering the motor. For the three cases on the goniometer that fit this description, open the two smaller ones. You wil find that there is a dial which you can turn by hand on of them; this will move kappa

Data Backup

There are 4 options to back up your data from our data disks: DVD Backup Instructions are available here Backup to Laptop Instructions are available here FTP Instructions are available here Firewire To copy data from our disks to your data storage device, type: rsync -av --modify-window=1 [source directory] [destination directory] This will let you copy files and gives you the added ability to update new files by issuing the command again. rsync copies any new files that came into the source directory and does not overwrite anything already backed up. For information on formating and partitioning external harddrives, go to Reformat Instructions. When setting up a firewire, follow this procedure: It would be useful to double check what a machine thinks it has mounted to it.Do a 'cat /proc/scsi/scsi' to check if there are any scsi devices attached. To release a scsi port: As Root: echo "scsi remove-single-device 2 0 0 0"> /proc/scsi/scsi where the number '2' designates which scsi port is occupied (get this number from 'cat /proc/scsi/scsi'). After verifying there is no scsi ports occupied, run cat /proc/scsi/scsi to make sure there is no attached devices. After verifying there is no attached devices, power on firewire and plug into USB2 or firewire port. (If you are mounting a firewire to X25-a, you need to plug your USB2 or firewire cable in Before you power up the firewire disk). At this point, just make sure that the firewire device has been recognized by the computer. Do a cat /proc/scsi/scsi to see if your device shows up. If it doesn't, then, as root, do a rescan-scsi-bus.sh. This should bring it up. After this, just type 'mount /computer_name/1394_data1', where 'computer_name' is the name of the machine you're mounting the disk to. Some quick remiders for firewire and such. Output from the following commands is useful. df -l dmesg cat /proc/scsi/scsi cat /proc/partitions grep kernel /var/log/messages (root only) "I/O error" or "File system read only" Firewire was unplugged before unmounted run 'fdisk -l /dev/sda' to see disk and partitions umount disk as root run 'dosfsck -av /dev/sd??' 'rescan-scsi-bus.sh -r' removes disconnected disks that may still be in 'df' or '/proc/partitions' As a last resort, you can reset the firewire driver by: /modprobe -r sbp2; /modprobe -a sbp2 To look at a list of the modules: /sbin/lsmod "Permission denied" 'chmod 777' changes ownership to read,write,execute for you "Device is Busy" run 'pwd' are you in the device? run 'sbin/fuser -vum /x__-_/1394_data1' to see what is using it, and kill it or -vumk option to kill automatically If the previous method does not work, due to that speedy gam_server, try running '/sbin/fuser -vumk /x__-_/1394_data1 ; umount /x__-_/1394_data1' this should kill it automatically and unmount the device before the daemon has a chance to fire it back up. "No Such Device" run 'cat /proc/scsi/scsi' is the device there? run 'rescan-scsi-bus.sh' Make sure the firewire is "off" when it is plugged into x25-a.

Networking

Proxy Configuration To reconfigure proxies for Mozilla Go to the 'Edit' Menu and choose 'Preferences'. Find the 'Advanced' category and choose 'Proxies'. At this point, you can manually or automatically configure the proxy. For manual configuration, enter under HTTP Proxy 192.168.1.3 and Port 3128 For automatic config, type the address http://security.bnl.gov.proxy/cfg.pac Check Printer Status To check on printer status, in web browser, type http://w04.nsls.bnl.gov:631 This brings up the print server for all the linux machines.

Misc. Stuff

Unix/Linux Commands: To remount all disks, type (as root), mount -a -t nfs To use scp: scp -r /source_directory /destination_directory This lets you file transfer pretty easily between two machines. Ion Chamber Operation (_ )=recommended values Plug in Change "Display" to preset Use "Select" & "Advance" to change count time multiple (10*10^1) Change "Display" to A Select time base (0.01) Press "Count" to see time is correct Adjust dwell knob for pause between counts Change "Display" to B for counts Change IC Plus voltage & gain (V=400,G=4)
