+
+ 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

+
+ > config listen 0
+
+ Of course this command can also be run on a already open client.

+
+ !!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
+
+ 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.
+
+
+ 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.
At line 162 added 17 lines.
+ 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.
