	The modern concept of an Energy Recovery Linac allows providing large electron currents at large beam energy with low power consumption. This concept is used in FEL’s, electron-ion colliders and electron coolers. CERN has started a Design Study of an ERL Test Facility with the purpose of 1) studying the ERL principle, its specific beam dynamics and operational issues, as relevant for LHeC, 2) providing a test bed for superconducting cavity modules, cryogenics and integration, 3) studying beam induced quenches in superconducting magnets and protection methods, 4) providing test beams for detector R&D and other applications. It will be complementary to existing or planned facilities and is fostering international collaboration. The operating frequency of 802 MHz was chosen for performance and for optimum synergy with SPS and LHC; the design of the cryomodule has started. The ERL Test Facility can be constructed in stages from initially 150 MeV to ultimately 1 GeV in 3 passes, with beam currents of up to 80 mA. Parameters to serve the above-mentioned purposes are well defined and possible lattice designs have well advanced.

THPRI115	Measuring and Aligning Accelerator Components to the Nanometre Scale	4049
	N. Catalán Lasheras, H. Mainaud Durand, M. Modena CERN, Geneva, Switzerland
	First tests have shown that the precision and accuracy required for linear colliders and other future accelerators of 10 micrometers cannot be reached with a process based on independent fiducializations of single components. Indeed, the systematic and random errors at each step add up during the process with the final accuracy of each component center well above the target. A new EC-funded training network named PACMAN (a study on Particle Accelerator Components Metrology and Alignment to the Nanometer scale) will propose and develop an alternative solution integrating all the alignment steps and a large number of technologies at the same time and location, in order to gain the required precision and accuracy. The network composed of seven industrial partners and nine universities and research centers will be based at CERN where ten doctoral students will explore the technology limitations of metrology. They will develop new techniques to measure magnetic and microwave fields, optical and non-contact sensors and survey methods as well as high accuracy mechanics, nano-positioning and vibration sensors.
