Abstract
| The first part of the presentation will summarize the overall cryogenic
performance and availability for Run 2. Main evolutions and effects on the
cryogenic system during Run 2 will be presented. The second part will focus on
the LS2, in particular the main maintenance and evolutions engaged. We will
present their expected effects on the global availability on one hand and their
expected influence on the cryogenic limitations with respect to the required
cooling power during Run 3 on the other hand. Finally, we re-formulate the
expected cooling power limitations taking into account the balance between 1.9 K
cooling power used for Inner Triplet and 4.5-20 K non-isothermal cooling power
used for Beam Screens. |
