Lines 14-16 were replaced by lines 19-21
- |TASP |6 Tesla |with goniometer, goniometer motors removed
- |TASP |9 Tesla |without goniometer unit
- |Rita-II |4 Tesla |with goniometer, goniometer motors removed
+ |TASP |6 Tesla |with goniometer, goniometer motors removed, distance to Be filter: > 20 cm
+ |TASP |9 Tesla |without goniometer unit, monochromator 2theta > 75, distance to Be filter[1]: > 22 cm\\7.9 Tesla: 2theta > 55 ?
+ |Rita-II |4 Tesla\\9 Tesla|with goniometer, goniometer motors removed\\without goniometer
Lines 18-21 were replaced by lines 23-31
- |HRPT |?? |force measurements to be redone
- |FOCUS |9 Tesla |distance magnet center to mono center 2 m, 2theta < 132 deg or magnet surface to guide surface > 0.9 m
- |TriCS |4 Tesla |
- |Morpheus |3.5 Tesla |with X-Y table, dist. to diaphragmas at least 250 mm
+ |HRPT |4 Tesla |without RC shielding [2]
+ |FOCUS |9 Tesla |magnetic rail and motor of radial collimator removed\\distance magnet center to mono center 2 m, 2theta < 132 deg or magnet surface to guide surface > 0.9 m
+ |TriCS |2 Tesla |due to problems with omega-encoder (from the forces 4 T is possible)
+ |Morpheus |3.5 Tesla |with X-Y table, dist. to diaphragmas at least 250 mm, omega motor not in use
+ |Morpheus |2 Tesla |with omega motor
+ [1|#1] on TASP: [MA09/taspFilterMA09.png]
+
+ [2|#2] on HRPT: [MA09/RCshielding.jpg][MA09/RCmotor.jpg]\\
+ The RC shielding (left picture) has to be removed. One of the pieces making trouble is probably the RC motor (right picture).
At line 22 added 2 lines.
+ On all other Instruments, MA09 can not yet be used.

Lines 25-27 were replaced by lines 37-44
- * The magnet seems not to work reliably with the lambda stage
- (2 quenches during an expt. in November 2006). The reason is not
- yet clear. A user claimed that the switch heater power is too low
+ * The magnet has a cold leak, occuring only occasionaly at low temperatures.
+ As a workaround the main vacuum has to be pumped constantly. (Oct 2006)
