| THXC01 | LHC Beam Instrumentation | 2630 |
| The LHC will have very tight tolerances on all beam parameters. Their precise measurement is therefore very important for controlling and understanding the machine. With over two orders of magnitude higher stored beam energy than previous colliders, machine protection is also an issue, with any beam losses having to be closely monitored. This presentation will aim to give an overview of the beam instrumentation foreseen for the LHC together with the requirements for initial and nominal operation. A summary of the main systems will be followed by a discussion of areas where there have been recent advances, such as in the measurement of tune, chromaticity and coupling. | ||

| THXC02 | Diagnostics for Commissioning LCLS | 2635 |
| The fist stage of commissioning of the Linac Coherent Light Source at SLAC has begun in April of this year with succesful transport of the beam from the new RF photoinjector throught to the first bunch compressor. Construction and installation is continuing and will culminate with first FEL light in 2009. The LCLS provides several diagnostic challenges for providing precision, single-pulse readback of beam size and position in order to tune for very low 1 micron emittances. Ultra-short subpicosecond bunches call for special techniques of bunch length measurement including coherent radiation monitoring and the transverse deflecting cavity. The latter is also used to measure time dependant emittance and energy spread of slices along the bunch, which are critical to the lasing process within the FEL. | ||
