between -200°C and +200°C to scan the lattice parameter and thereby change the energy of the incident beam. For some measurements, the highest energy resolution is not necessary and the neutron flux at the ... r crystals. This is done by creating a thermal gradient in the direction parallel to the incident beam. The average temperature of the CaF2 ...

Requesting beam time OrientExpress is a support instrument. It is not scheduled like other instruments. OrientExpress is not free to use at any time. A time request for OrientExpress must be submitted ... experiment under the same proposal number for your convenience. There are two further routes to request beam time on OrientExpress: If the sample ...

The beam monitor data exceeded this count limit several times and posed major problems in normalising the data ... This was used in the data save routines; the first twelve or so values were read from electronics (beam monitor, time etc.) and the ...
