The SRS: now just so much junk

Today was a rather surreal experience.

Now that the SRS has finally shut, and before the men with spanners start to dismantle the accelerator – some parts of which are over 40 years old – the site has been opened to staff (and the many ex-staff) for a full Sunday. It was a strange experience to come as a tourist to my own place of work, and even stranger that for the event the lab has decided to include a funfair, classic car rally, and birds of prey exhibition. I’m not really sure what any of that has to do with synchrotron science, but maybe it brings in the punters. Unfortunately, the bouncy castle and ‘megaslide’ (whatever that is) were both stolen last night, so the funfair consisted solely of rides next to our decrepit site stores building. I’m not quite sure why it’s best to put playing children near to piles of scrap metal, but there you go.

The celebratory aspect of the day seemed a bit misplaced to me, since there is nothing really to replace the facility, and more than a few people are being made redundant. It was doubly poignant for me as I’m leaving the lab myself in a week’s time, and I worked closely on the SRS for some years.

Oh well…

Of course, the open day was timed to come just after the last SR user meeting to be held at Daresbury. Besides the expected eulogies to the varied research that was done on the SRS, there was an interesting presentation by Jon Marangos, project leader of the ‘New Light Source‘ (what a terrible committee name that is). The science case has been completed, and is available in draft form for comment before final submissiong for funding for the design stage. Perhaps unsurprisingly, it calls for a high-repetition rate X-ray FEL suite (i.e. above 1 kHz), albeit without much technical definition that ties the experimental needs to hard accelerator parameters – the lack of which may or may not come back to bite as it did on 4GLS. Maybe it will get sorted out during the design phase.

Those ‘in the know’ realise that high repetition rate basically means superconducting cavities, since normal-conducting ones can only operate in pulsed mode under 1 kHz. And there are plenty of accelerators being built around the world that will do that – so won’t get funded in the UK. A superconducting design would be kind of nice, since I published a design for one of those a few months ago. Ok, so my design is based on ideas from a number of other people (WiFEL, LBNL etc.), but I think it’s quite good. Maybe they’ll ask me to carry on working on it even though I’m leaving.

I wonder if I can get some overtime at work by bursting into tears tomorrow? I’ll let you know.
