Modern hadron accelerators create and transport beams that carry MW-scale power or store GJ-scale energy. The Machine Protection Systems (MPS) that guard against both catastrophic failures and long-term performance degradation must mitigate errant beam events on time scales as short as several microseconds. Measurement systems must also cope with detection over many orders of magnitude in beam intensity to adequately measure and respond beam halo loss. Other issues, such as radiated signal cross-talk, also confound and complicate delicate measurements. These requirements place enormous demands on the MPS beam diagnostics and beam loss monitors. We will review the current state of MPS diagnostic systems for this class of accelerator, including SNS, ESS, FRIB, LHC, J-PARC, and SPIRAL-II. Specific designs and key performance results will be presented and discussed.

TUPF12	First Tests of a Micro-TCA-Based Downconverter Electronic for 5GHz Higher Order Modes in Third Harmonic Accelerating Cavities at the XFEL	HOM, higher-order-mode, electronics, cavity	337
	T. Wamsat, N. Baboi DESY, Hamburg, Germany
	Beam excited higher order modes (HOM) in 3.9GHz accelerating cavities at the European XFEL are planned to be used for beam position monitoring. The specifications of the monitors have been defined during an extensive study on the 3.9GHz module at FLASH. Selected HOMs for precision measurement are located around 5440MHz and 9040MHz. An electronics developed by FNAL has been recently installed at FLASH* and provides a basis for the XFEL electronics. The paper will present the design and first test of the hardware for the μTCA (Micro Telecommunications Computing Architecture) standard used for the XFEL. The hardware consists of three different Rear Transition Modules (RTM), two four channel downconverter RTMs (5GHz and 9GHz) and a third RTM with two phase locked loop synthesizers on board for LO generation. Presently the 5GHz and the PLL RTMs are under construction. The first measurements with these cards will be presented. N.Baboi, N.Eddy at al., this conference *N.Baboi, N.Eddy at al., this conference

	Funding: *Work supported by the BMBF through 05K13RDA The S-DALINAC is the superconducting linear accelerator of the Institut für Kernphysik at Technische Universität Darmstadt. It delivers an electron beam with energies up to 130 MeV. In order to get a short-time response about occurring beam losses and their locations a new system was tested and installed. The setup is based on beam loss monitors of Bergoz company using two pin-diodes to record primary electrons as well as secondary radiation in a coincidence set-up. The readout is done using a self-developed system of a supply unit including differential line-drivers and fast counting cards compatible to our EPICS-based control system.

WEPF09	Introduction to the Test Result of Turbo-ICT in PAL-ITF	laser, diagnostics, electron, pick-up	553

	Pohang Accelerator Laboratory (PAL) built a PAL-ITF (Injector Test Facility) at the end of 2012 to successfully complete PAL-XFEL (X-ray Free Electron Laser) in 2015. The PAL-ITF is equipped with various kinds of diagnostic equipment to produce high-quality electron bunches. The three main parameters that an injection testing facility should measure are charge, energy and emittance. Although ICT and Faraday Cup were installed to measure beam charge, the noise generated in a klystron modulator not only interrupted accurate measurement but prevented low charges under tens of pC from being measured. Due to the changes in the overall voltage level of ITF, integration of ICT measured value failed to maintain perfect accuracy in terms of methodology (measured value continuously changed by ± 5pC). Accordingly, to solve the noise problems and accurately measure the quantity of electron beam charge, Turbo-ICT was installed. This paper focuses on the processes and test result of electric bunch charge quantity measurements using Turbo-ICT.
