Here’s a short guide to solve the problems you might encounter while doing an experiment at ID10-EH1. In general, the floor coordinator (phone 25-25) will help you with technical problems any time. However, you might save some time by looking here.

There are several SPEC applications that can be run at ID10-EH1 Linux workstation. Main applications are "eh1_exp", "eh1_optics", "eh1_opiom", ... For simplicity in the following examples we will mention only the "eh1_exp" application.

List of known problems:

1)

? The konsole window running "eh1_exp" application is dead (not responding).

! Open another konsole window, login to ting computer (ssh ting) and write in the konsole prompt ps -u eh1_exp From the list of jobs, identify the dead "eh1_exp" process and type kill -9 pid where pid is the process id of the dead job in the list. After this, start a new "eh1_exp" by typing eh1_exp in the konsole prompt at MAX computer.

2)

? A motor will not move. An error message is given in id10b.

! Probably the soft limits are reached. In general, these limits must not be changed since they prevent the motors to hit a hard limit (end of spindle, limited stroke etc.). If it is obvious that no such hard limits are present, the soft limits can be changed by typing set_lm motorname 0 360 that will set the soft limits of the motor to 0 (min) and 360(max).

! Maybe an ICEPAP is not switched on.

! Type reconfig   to reconfig the spec

3)

? A motor seems to move (the positon listed by typing wm motorname has changed) but physically it doesn’t move.

! Identify the motor in the experimental hutch. Is the cable connected? If not find the right cable and plug it in (REMEMBER TO SWITCH OFF THE ICEPAP RACK BEFORE CONNECTING OR DISCONNECTING ANY MOTOR CABLE !) If everything looks normal but the motor still doesn’t move inform the beamline staff asap.

4)

? I cannot open the ID10_EH1 shutter by typing shopen.

! The search procedure is not completed.

! Otherwise, call the floor coordinator (25-25)

5)

? The ID10-EH1 beamshutter is open but there appears to be no beam in the hutch.

! The front end is closed. This is the case if the light panel "FRONTEND" is out. This means that the machine is refilling or that "automatic mode" setting in "idappli" expired (after 144hrs). Reopen it by clicking the "OPEN FRONTEND" button in "idappli"

6)

? I cannot open the front end.

! See 5). Otherwise call the machine control room (24-90) or the floor coordinator 24-24 and ask them to open it.

7)

? The beam didn’t return after a refill or an intervention on the machine side.

! Check if the undulator gaps are closed in "idappli". If not, look under Undulators in the machine and optics hutch section of this user guide. If the undulators are not moving call the machine control room at 24-90.

Things I shouldn't do at ID10-EH1

:-( Disconnect or connect any motors without authorization from the staff

:-( Install or un-install software on the computers without authorization

:-( Leave the Chemistry lab in a mess
