11.7 L-He Cryostat problem: update 3

2011-11-09: The liquid-helium cryostat is currently not available due to the serious crash suffered during a beamtime of last May 2011. It has been necessary to sent it back to the supplier for repair. Date of dispatch: January 2012. At the moment, measurements can be performed with the sample kept at room temperature (RT) only.

11.6 L-He Cryostat problem: update 2

2011-09-06: The liquid-helium cryostat is currently not available due to the serious crash suffered during a beamtime of last May 2011. It has been necessary to sent it back to the supplier for repair. Expected delivery time: end of 2011. At the moment, measurements can be performed with the sample kept at room temperature (RT) only.

11.5 Phoibos150 2D-CCD detector: problem solved

2011-09-06: New MCPs and Phosphoros screen have been recently installed in the 2D-CCD detector of our SPECS Phoibos 150 electron analyzer in order to solve the shadow problem generated during a beamtime in February 2011.

11.4 L-He Cryostat problem: update 1

2011-07-04: The liquid-helium cryostat is currently not available due to the serious crash suffered during a beamtime of last May 2011. It has been necessary to sent it back to the supplier for repair. Expected delivery time: unknown. At the moment, measurements can be performed with the sample kept at room temperature (RT) only.

11.3 L-He Cryostat problem

2011-05-23: The liquid-helium cryostat has suffered a serious crash and it is currently not available. Recovery time: unknown. Therefore the installation of the new motorized 5 degree of freedom sample holder on the cryostat is postponed to the time the cryostat will be back.

11.2 New motorized 5 degree of freedom sample holder

2011-05-09: A new 5 degree of freeedom sample holder with motorized azimuthal angle (attocube rotator based) has been successfully tested. It is ready to be definitively assembled in our liquid helium cryostat. Work planned in June 2011.

11.1 Phoibos150 2D-CCD detector problem

2011-02-15: The 2D-CCD detector of our SPECS Phoibos 150 electron analyzer has suffered repeated exposures to a huge amount of electron counts and now it presents a shadow problem on the low kinetic energy side of the detector.
