Date: August 22, 2006 - August 24, 2006
Time: 4:00 pm - 5:00 pm

We have an unusually busy schedule next week: we have 3 accelerator seminars three days in a row starting Tuesday, August 22nd. All seminars begin at 4:00 pm in Orange room.

For Wednesday and Thursday seminars, ILC department agreed to provide cookies.


Below are announcements for three SLAC Accelerator Seminars ==================================================
Tuesday, August 22nd, 4:00 pm, Orange Room


Steve Peggs (BNL)
will give a talk on

"Accelerator Science at the LHC Frontier"



==================================================

Wednesday, August 23rd, 4:00 pm, Orange Room

Nina Golubeva (DESY)
will give a talk on

"Beam optics for Free-Electron Laser in Hamburg (FLASH, former VUV-FEL) facility: Theory and practical applications"

Abstract:
Different options for the beam optics of the linac and the undulator focusing lattice of FLASH were developed already before the start of the accelerator commissioning.
In this talk the theoretical motivations and practical usefulness to have not a one but a set of optical solutions will be given, and for the optics which were already applied, the effect of that on machine operations and comparison with measurements will be discussed.

==================================================

Thursday, August 24th, 4:00 pm, Orange Room

Vladimir Balandin (DESY)
will give a talk on

"Post-linac collimation systems for the European XFEL and
for FLASH facility"

Abstract:
The post-linac collimation system of FEL facility must protect the undulator modules from damage which can be made by mis-steered and off-energy beams in the case of machine failure.
During routine operations it should remove with high efficiency off-momentum and large amplitude halo particles, which could be lost inside undulator modules and become source of radiation-induced demagnetization of the undulator permanent magnets.
In this talk the collimation systems of the European XFEL Project and of FLASH facility (already in operation) will be presented and their theoretical design principles will be discussed.
