The 42 km long CLIC Drive Beam Decelerator (DBD) will decelerate beams of electrons from 2.4 GeV to 240 MeV. ASTeC in collaboration with CERN has developed a novel type of tunable permanent magnet quadrupole for the DBD. Two versions of the design were produced, for the high-energy and low-energy ends of the DBD respectively. This paper outlines the design of the low-energy version, which has a tuning range of 3.5-43 T/m. A prototype was built at Daresbury Laboratory (DL) in 2013, and extensive magnetic measurements were carried out at DL.

Six UK institutes are engaged in a collaborative R&D programme with CERN aimed at demonstrating key aspects of technology feasibility for the Compact Linear Collider (CLIC). We give an overview and status of the R&D being done on: 1) Drive-beam components: quadrupole magnets and the beam phase feed-forward prototype. 2) Beam instrumentation: stripline and cavity beam position monitors, an electro-optical longitudinal bunch profile monitor, and laserwire and diffraction and transition radiation monitors for transverse beam-size determination. 3) Beam delivery system and machine-detector interface design, including beam feedback/control systems and crab cavity design and control. 4) RF structure design. In each case, where applicable, we report on the status of prototype systems and performance tests with beam at the CTF3, ATF2 and CesrTA test facilities, including plans for future experiments.

The Versatile Electron Linear Accelerator (VELA) facility will provide enabling infrastructures targeted at the development and testing of novel and compact accelerator technologies, specifically through partnership with industry and aimed at addressing applications in medicine, health, security, energy and industrial processing. The facility has now been commissioned at Daresbury Laboratory and the facility is now being actively utilised by industrial groups who are able to take advantage of the variable electron beam parameters available on VELA to either demonstrate new techniques and/or processes or otherwise develop new technologies for future commercial realisation. Examples of which to be presented include; demonstration of a new cargo scanning process, characterisation of novel, high performance beam position monitors, as well as other technology development applications.

STFC, in collaboration with Diamond Light Source, are designing and building a 15.5 mm period, 1.26 T superconducting undulator. This paper describes the modelling of the undulator, using Radia and Opera. Extensive numerical modelling has been carried out to simulate the effect of manufacturing tolerances on the quality of the magnetic field, in order to meet the demanding 3° rms phase error specification.
