Mike
Bailey has recently been appointed as ERL Prototype site manager. This
role involves, amongst other things, coordination of the construction activities
in the Tower and managing the Permit to Work system. This is all part of
the overall safety planning and it will ensure disparate areas of work
in the Tower conform to the ERLP safety plan.MoUs
Memoranda of Understanding have recently been signed between CCLRC and both Jefferson Laboratory (JLab) and Stanford Linear Accelerator Centre (SLAC). The photographs below show John Wood signing the MoU at Jefferson Laboratory and his subsequent tour of the Laboratory.
4GLS INDUSTRY MEETING
The first 4GLS Industry Meeting was held at the Radisson Edwardian Hotel in Manchester on 23rd September 2004 . The lively meeting attracted over 70 delegates representing firms interested both in the advanced technology required for 4GLS and the scientific exploitation of 4GLS. Application areas represented were particularly diverse spanning pharmaceuticals, through skin care products to nano materials and catalysis.
The day, which was chaired by John Garside (VC, UMIST), opened with thought-provoking presentations from Andrew Leslie (LMB Cambridge), John Stageman (AstraZeneca) and David Hughes (DTI). These laid the foundations for discussion and debate on the general issues of linking activities and emerging techniques to emerging markets, innovation, exploiting the electromagnetic spectrum, international competitiveness and long term development potential. The technical characteristics of 4GLS were presented by 4GLS Team members and then the meeting split into three parallel sessions to discuss, in detail, the specific challenges and opportunities presented by 4GLS in the areas of pharmaceuticals, catalysis and semiconductors. Feedback from the parallel sessions fostered further wide-ranging discussions, complemented by a presentation from Alan Todd (AES and Chair of the Industrial Advisory Board for the Jefferson Laboratory FEL) on the approaches taken to foster industrial use of the JLab FEL. The day closed with a question and answer session followed by an excellent meal.
The meeting was followed on the 24th of September by tours of Daresbury Laboratory. These were well attended and covered not only the site for the ERL prototype but also SuperSTEM, HPCx, DARTS and the SRS linac, booster and main ring. The tours finished with lunch in the atrium of the new Daresbury Innovation Centre.
The meeting was organised and sponsored by the NWDA and much credit should go to Pamela Harbron (NWDA) for her hard work over many months.
START-TO-END-SIMULATIONS
The first start-to-end simulations for transportation of the electron beam around ERLP have been completed. To verify the predicted performance of the ERLP and its free electron laser (FEL), an integrated study of the overall beam dynamics of the accelerator has been carried out. This start-to-end (S2E) modelling involves tracking a large number of particles from the photoinjector cathode through the FEL and to the electron beam dump, including the effects of acceleration, compression, FEL interaction and deceleration.
The simulation codes ASTRA, ELEGANT and GENESIS have been utilised. Overall, the S2E simulations predict that ERLP will produce lasing in the oscillator FEL as envisaged from analytical models, and that the beam can be recovered without significant transport losses. Work is now in progress using a new code to the Laboratory, known as GPT, to verify that the space charge emittance growth in the low-energy (8.35 MeV) injector region is acceptable.
