	The design guide-lines of RF Linacs to fulfill the requirements of high spectral density Inverse Compton Sources for the photo-nuclear science are mostly mutuated from the expertise coming from high brightness electron Linacs driving X-ray FEL's. The main difference is the quest for maximum phase space density (instead of peak brightness), but many common issues and techniques are exploited, in order to achieve an optimum design and lay-out for the machine. A relevant example in this field is the design of the hybrid C-band multi-bunch RF Linacs for the ELI-NP Gamma Beam System, aiming at improving by two orders of magnitude the present state of the art in spectral density available for the gamma-ray beam produced.

MOPP036	Estimation of the Thermal Load and Signal Level of the ESS Wire Scanner	linac, DTL, detector, cryomodule	137
	B. Cheymol ESS, Lund, Sweden
	The European Spallation Source (ESS), to be built in the south of Sweden, will use a 2 GeV superconducting linac to produce the worlds most powerful neutron source with a beam power of 5 MW. A number of wire scanners will be used to characterize the beam transverse profile. The design of the wire has to cope with the high power density of the beam and must satisfy the overall measurement robustness, accuracy and sensitivity for the commissioning and the regular retuning phase of the ESS linac. This paper describes the preliminary design of the wire scanner system in the normal conducing linac as well as in the superconducting linac.

	An X-band RF transverse deflector composed of two 1-m-long X-band deflecting structures has been recently commissioned at the Linac Coherent Light Source (LCLS) at SLAC National Accelerator Laboratory. Located downstream of the FEL undulator, this device provides electron beam longitudinal phase space diagnostics in both time and energy which enables reconstruction of the X-ray FEL power profiles with an unprecedented resolution. This talk reports on the progress of this new LCLS X-band transverse deflector, first usage experience and measured results.
