Difference between version 19 and version 1:
Lines 1-4 were replaced by lines 1-3
- || Instrument || field direction\\parallel to beam || field direction\\perpendicular to beam
- |SANS-I | 11 Tesla | *
- |SANS-II| * | *
- |AMOR | 2 Tesla* | *
+ max. allowed Force
+ |horizontal|200N
+ |vertical|500N
Line 6 was replaced by lines 5-34
- * to be reevaluated
+ || Instrument || field direction\\parallel to beam || field direction\\perpendicular to beam || Conditions
+ |SANS-I | 11 Tesla | 11 Tesla | without spin flipper
+ |SANS-II| 11 Tesla | 11 Tesla |
+ |AMOR | 2 Tesla * | * |
+ |RITA-II| 11 Tesla | 11 Tesla | 45 deg < a2 < 100 deg, d = 450 mm
+ (*) to be reevaluated, ask [Markus Zolliker]
+
+ On all other Intruments, MA11 can not yet be used.
+
+ !Remarks for SANS-II
+ Force measurements (29.5.08):
+ * 8 kg at 4 Tesla perpendicular
+ * 8 kg at 5 Tesla parallel
+ It seems that most of the force is induced by a steel ring on the valve before the detector tank.
+
+ With new detector gate valve (18.8.2015), at 7.8 Tesla:\\
+ horizontal (beam direction) < 50 N, ~ 80 N (perpendicular), 220 N vertical\\
+ extrapolate forces at 11 T: 160 N horiz., 440 N vertical
+
+ ! Remarks for RITA-II
+ Monochromator sample distance at least 450 mm
+
+ [MA15RitaRestrictions/SampleTableDistance.jpg]\\
+ How the distance has to be measured.
+ In this example the distance is around 400 mm.
+
+ Force measurements 14.7.2009 at 8 Tesla:
+ * 10 kg horizontal
+ * < 5 kg vertical
+ Extrapolation for 11 Tesla: 20 kg
