| + and on weekends, there is only very limited technical support. In order to |
| + minimize beam time losses, some rules have been established: |
| Lines 8-15 were replaced by line 9 |
| - ''Restrictions concerning magnets and/or dilution refrigerator experiments'' |
| - * On weekends or holidays, is not possible to start magnet or dilution |
| - refrigerator experiments |
| - * Support during weekend or in the evening may not be provided (there is no |
| - sample environment stand-by). If problems occur, it should be tried to |
| - contact the sample environment staff, but not during the night |
| - (10 p.m. - 8 a.m.). In the case that the contact can not be established, |
| - the experiment might have to be suspended until the next working day. |

| Lines 18-25 were replaced by lines 12-16 |
| - ''Restrictions concerning dilution refrigerator experiments'' |
| - * On weekends or holidays, sample changes are not possible |
| - * Experiments starting on Fridays (or at a day before a holiday) are only |
| - allowed at the beginning of a beam block, i.e. when the sample can already |
| - be mounted the day before. |
| - * The sample must be ready a workday before starting the experiment, except |
| - for the case where the stick is already used immediately before. In this |
| - case the rules for sample changes apply. |
| + ''Dilution refrigerator experiments'' |
| + * Sample changes must be done on working days |
| + * The sample must in general be ready (put on/into a suitable holder) |
| + in the morning of a workday before starting |
| + the experiment, except when the stick is already used immediately before. |
| Lines 27-28 were replaced by lines 18-22 |
| - sample must start before 8 a.m. Be aware that a delay of a working day |
| - may occur after a sample change. |
| + sample must start early in the morning. |
