As of Aug 5. 2003, C49 configures the b2, tune and coupling drift compensation cards during a load or file activate.  There should be no need to configure these cards manually.  These instructions are left for historical purposes.

Loading 465 for tune and coupling drift compensation

C:QFB2

C:QDB2

C:SQB2

C:SQ0B2

The proper configuration of the card is shown here. 

If we need to reconfigure, we should do this by copying C:SFB2 (which is configured by C49) into the card that needs to be loaded.   The is done from page I14.  In the menu at the top left of the page, select 'Copy Module'.  Use C:SFB2 as the source, and the target card as the destination.  

The above procedure will only configure the card.  We will then have tables (F(t) and H(i) tables) that were meant for the sextupoles loaded into the quad or skew quad circuits.  The proper tables will get loaded when we change states in the sequencer.  The front porch tables will get loaded when we 'Goto Injection Porch'.  The unwind tables will get loaded just before we ramp. 

If you need to force the front porch tables to load without going through the sequencer, follow this procedure.  Make sure T:FTTIME represents the length of the previous flattop (in seconds).  Make sure T:BPTIME represents the length of time of the previous back porch (in seconds).  If these times are not correct, just set them from the parameter page.  Then, set T:CHRCOM to 6 (this loads the tune front porch tables H-table 1).  Then set T:CHRCOM to 11 (this loads the coupling front porch tables H-table 1).  Also, setting T:CHRCOM to 1 will load the sextupole front porch tables.
