|
|
April 2016 |
The collimation system is commissioned for the 2016 LHC operation at a betastar of 40 cm, with the gaps at the primary collimators as small as 2.1 mm and a cleaning inefficiency of 3e-4.

|
October 2015 |
A particle tracking workshop was held on the 30th October to review the status of the different tools for collimation studies, as well as results of benchmarking of simulations against measurements. Indico link here.

|
May 2015 |
The collimation system has been commissioned for the full machine cycle. The settings calculated from the alignments at each stage have been verified via beam loss maps.

|
July 2014 |
All collimators for LHC Run II have been installed. |

February 2013 |
Collimator Quench Test. Achieved up to 1.05MW of peak power loss during the test within 5-10seconds, no quench was recorded. Measured quench limit for collimator losses rised by a factor of 2. |
