+ !! six
+
+ six is an alternative to the standard Java SICS commandline client. Why an alternative SICS client?
+
+ • It is much faster
+
+ • It does not need the X window system
+
+ • It connects automatically to the instrument if you are logged into the instrument computer

+ To turn it off again, type
+
+ > config listen 0
+
+ Of course this command can also be run on a already open client.

+ Alternatively use

+ To synchronize the instrument parameter execute the command sync

+
+ ----
+
+ !!2-axis and 3-axis mode
+
+ The spectrometer can be run in two modes, 2-axis and triple-axis.
+
+ There are 2 triple-axis modes: ki and kf. Usually the kf option is used.
+
+ There is one 2-axis mode: elastic.
+
+ To read which mode the spectrometer is in write
+
+ > tasub const
+
+ To change the mode write for instance
+
+ > tasub const elastic
+
+ ----
+
+
+
+ !!Lambda/2 mode
+
+ To use Lambda /2 neutrons without changing A2 just divide the monochromator d-spacing by a factor of 2, i.e. go from 3.354 A to 1.677 A
+
+ > tasub mono dd 1.677
+
+ > tasub update
+
+
+ Next drive Ei and Ef to 4 times the initial energy.
+ For example for 5 meV = 4.04 A drive Ei and Ef to 20 meV =2.02 A
+
+ Note, that the primary instrument, i.e. the monochromator will not move. The analyzer however will move, so make sure that any field from a magnet is set to zero.
+
+
+ To go back to 5 meV
+
+ > tasub mono dd 3.354
+
+ > tasub update

+
+ !! Disabling and enabling motors
+
+ For all the motors from the DeltaTau controllers, to enable them in SIX you just type, for example
+
+ sgu enable 1
+
+ and to inhibit them, type e.g.
+
+ sgu enable 0
+
+ To list which (of the DeltaTau) motors are enabled or inhibited, just type
+
+ enable
+
+
+ To disable or enable the sample table, i.e. the morors tu,tl,sgu and sgl you can use the commands disabletable and enabletable
At line 191 added 2 lines.
+ To disbale or enable the slits use disbaleslits or enableslits.
+ You have to disable the motors, before you physically disconnect them, i,e. when removing the sample table or the slits in case of cryomagnet operation.
At line 192 added 44 lines.
+
+ If you enable or inhibit the motor manually using the hardware switch, it may take up to 30 seconds for SIX to update this parameter and to realise what you've done.
+
+ ML has also stopped SIX from automatically enabling all the motors when SIX is started.
+
+ -----
+
+ !!Filters
+
+ Be and BeO after the sample and before the analyzer tank filters can be moved in and out of the beam by the following commands:
+
+ bef in
+
+ bef out
+
+ The rotation of the filters is controlled by the command brot.
+
+ -----
+
+
+ !!Threshold for PSI counter box
+
+ The PSI counterbox el737 is accessible from sics.
+
+ The following commands are available.
+
+
+ el737 threshold
+
+ reads the current threshold
+
+ el737 threshold value
+
+ sets a new threshold.
+
+ Typical values are 20 to 100. These numbers roughly correspond to the proton current on SINQ.
+
+ This threshold prevents collecting background data in case of no beam or a very low beam.
+
+ The analog in TASCOM was the command CIBO and manual setting of the box.

At line 208 added 5 lines.
+ In case of problems with the communication between sics and sea you can try the following.
+
+ In sics use the command connect_sea.

-
- kill the portserver
-
- Look for process Serportserv, notice its PID and execute:
-
- kill -9 PID
