The Spallation Neutron Source, a neutron scattering user facility based on a 1.4MW proton accelerator, has been in operation since 2006. The accelerator beam diagnostics were designed, in large degree, with commissioning unknowns in mind. Today we face new challenges to support stable 1MW beam power operations and accelerator upgrade for even higher power. The beam instrumentation problems span a range from mitigating obsolescence of many electronics to developing new techniques for measuring beam parameters important for high power operation. This report describes several examples of the ongoing work: development of new electronics for Beam Position Monitor (BPM) and Beam Loss Monitor (BLM) systems to replace the aging designs; development of large dynamic range and high precision beam phase space characterization tools to facilitate the model based accelerator tuning.

  At the National Institute of Radiological Sciences (NIRS), we have been developing the rotating-gantry system for carbon-ion radiotherapy. This system is equipped with a three-dimensional pencil beam scanning irradiation system. To ensure the treatment quality, calibration of the primary dose monitor, range check, dose rate check, machine safety check, and some mechanical tests should be performed efficiently. For this purpose, we have developed a measurement system dedicated for quality assurance (QA) of this gantry system. The ion beam's dose output was calibrated by measurement using an ionization chamber. A Farmer type ionization chamber was inserted into the center of a plastic water phantom. The thickness of the phantom could be changed so that it employs both calibration of the output at entrance and output checking at center of the irradiation field. The ranges of beams are verified using a CCD camera and a scintillator system. From the taken images, maximum gradient points are determined by some image processing and compared with reference data. In this paper, we describe consideration of the daily QA for the rotating-gantry.

  • J.X. Wu
    IMP/CAS, Lanzhou, People's Republic of China
  An accelerator-driven subcritical system (ADS) project has been launched in China in 2011, which aims to design and build an ADS demonstration facility with the capability of more than 1000 MW thermal power in multiple phases lasting about 20 years. The driver LINAC has two injectors in parallel to provide up to 10 mA cw proton beam with the energy of 10 MeV. The injector II is constructed by IMP and its beam commissioning was started since 2013 with the 560 keV RFQ prototype. In 2014, more than 10 mA cw beam after RFQ with the energy of 2.1 MeV was successfully commissioned. In 2015 it aims at providing 5 MeV cw beam after the first CM. This paper will introduce the beam instrumentation on the C-ADS injector II. Also the beam commissioning and the challenges encountered will be described as well.  
MOPB035 Beam Profile Measurements with a Slit-Faraday Cup and a Wire Scanner for a Newly Developed 18 Ghz Superconducting ECR Ion Source and its LEBT 1
  • H.J. You, W.I. Choo, S.O. Jang

  In this presentation we show results of beam profile measurements by a slit-Faraday cup system and a wire scanner. Argon 8+ beams were generated in a new liquid helium-free superconducting electron cyclotron resonance ion source (ECRIS)*, The ECRIS, named SMASHI, was successfully developed at the National Fusion Research Institute in 2014**, and in the future it will be dedicated for highly charged ions matter interaction research facility (HIMIRF). Before designing and constructing HIMIRF terminals after low energy beam transport(LEBT), it is necessary to characterize the beam properties of the source and its LEBT line. The beam profile measurements have been done after an analyzing dipole magnet(DM). The slit-Faraday cup and the wire scanner were installed at 25 cm and 120 cm from the exit flange of AM, respectively. Between the two diagnostics an Einzel lens was positioned to control the focusing of diverged beams. Here, with the measurements we checked the present beam alignments in the LEBT, and studied the dependence of beam profile variation on the operations of beam optics such as steering magnets and Einzel lens..

MOPB050 Overview of Applications and Synergies of a Generic FPGA-Based Beam Diagnostics Electronics Platform at SwissFEL 1
  • W. Koprek, B. Keil, G. Marinkovic
    PSI, Villigen PSI, Switzerland
  For SwissFEL electron beam diagnostics, we combine application-specific detectors and front-end electronics with a common solution for digitization, interfacing and FPGA-based digital signal processing. Many key components and standards we use were initially developed by PSI for the European XFEL BPM system, but are equally suited for a broad range of SwissFEL diagnostics systems with little or no modifications. Examples are e.g. the FPGA signal processing hardware and firmware/software, ADC and DAC boards, interface boards or peak detection front-end electronics. By following a modular generic hardware and firmware/software design approach, we can cover a larger number of different monitor types with moderate development effort. Applications of our generic platform include BPMs, bunch length monitors, beam arrival time monitors, beam loss monitors, and digital laser phase locked loops (PLLs). This paper gives an overview of the design, present and future applications of our generic platform, discussing the synergies and differences of the required hardware, firmware and embedded software solutions.

FACET-II is a prospective user facility at SLAC National Accelerator Laboratory. The facility will focus on high energy, high brightness beams and their interaction with plasma and lasers. The accelerator is designed for high energy density electron beams with peak currents of approximately 50 kA (potentially 100 kA) that are focused down to below 10x10 micron transverse spot size at an energy of 10 GeV. Subsequent phases of the facility will provide positron beams ~5-10 kA peak current to the experiment station. Experiments will require well characterised beams however the high peak current of the electron beam can lead to material failure in wirescanners, optical transition radiation screens and other instruments critical for measurement or delivery. The radiation environment and space constraints also put additional pressure on diagnostic design.

Solaris is a third generation light source recently constructed at the Jagiellonian University in Kraków. The installation of the 600 MeV S-band linear accelerator with thermionic RF gun and transfer line as well as the 1.5 GeV storage ring is now complete. In November 2014 subsystem tests and conditioning of the Solaris linac were started. A 300 MeV electron beam at the end of the linac was observed for the first time in February 2015 after which the machine was shut down for 2.5 months to complete transfer line and storage ring installation. In May the commissioning of the linac together with the transfer line and storage ring began. The beam was soon observed on the YAG screen monitor, installed at the injection straight in the storage ring. The beam current measured with the fast current transformer in the transfer line was 8 mA over 180 ns, at 360 MeV. The commissioning of the machine is still in progress and preliminary results of Solaris are presented.
