[jpg]20060123(000).jpgI guess I just took this to prove that some work took place on the trip.  You can see the snow outside.  The many laptops connected through extension leads and adaptors turned the floor of the room into a kind of death trap or spider's web...
[jpg]20060126(000).jpgBEST PHOTO EVER
[jpg]20060126(001).jpgOne morning I went for a walk around the laboratory grounds.  Here you can see the nearby mountain above the buildings.
[jpg]20060126(002).jpgAnother view of the lab from a different direction.
[jpg]20060126(003).jpgLooking behind me, I found that I was walking beside the electron linac.
[jpg]20060126(004).jpgPicnic area!
[jpg]20060126(005).jpgStart your day the cyrogenic way with a refreshing can of liquid nitrogen.
[jpg]20060127(000).jpgInside the warehouse where the 150MeV FFAG accelerator was located.  For more on this see the FFAG tour page...
[jpg]20060127(015).jpgIt is quite common in Japan to have pools of water surrounding the buildings (offices in this case).  The outside part had frozen.
FFAG Tour [jpg]20060127(001).jpgLooking into the ring from the outside through a gap between the magnets.
FFAG Tour [jpg]20060127(002).jpgIn order to get inside the ring we have to cross this filmsy aluminium ladder.  This is made more difficult by the fact the entire thing is now inside a concrete block structure for radiation shielding and the ceiling is not particularly high.  The one taking the assault course here is Mike Zisman, leader of the scoping study accelerator working group.
FFAG Tour [jpg]20060127(003).jpgView from on top of that ladder.  The strip lights unfortunately dazzle my camera, but below you can see the cyclotron and injection line with four of the (ten?) magnets of the ring behind.  I can't work out whether the slight blurring in this picture was due to my hand or the ladder shaking.
FFAG Tour [jpg]20060127(004).jpgThat injection line again, featuring a quadrupole triplet and what I presume to be a load of diagnostics.
FFAG Tour [jpg]20060127(005).jpgCyclotron on the right, water cooling splitter on the left.
FFAG Tour [jpg]20060127(006).jpgApparently one of the parts of the accelerator got warmer than expected and needed a bit of additional cooling.  Air cooling, in this case, was added with a bunch of 12" fans.
FFAG Tour [jpg]20060127(007).jpgThe light-coloured pipes have water flowing in them, which goes out to cool various coils and returns to this splitter again.
FFAG Tour [jpg]20060127(008).jpgPipes.  Pressure gauge.  Valves.
FFAG Tour [jpg]20060127(009).jpgSo we went around the outside of the ring again and had to step over this wire trench.  They seem to have enough wires.
FFAG Tour [jpg]20060127(010).jpgExtracted beam line (also with a quadrupole triplet on it).  The main ring bends away behind.
FFAG Tour [jpg]20060127(011).jpgThis is closer to the magnet where the extracted line branches out.  I've forgotten exactly what that handle does.  I think it seals off the vacuum of the main ring from the extraction line.
FFAG Tour [jpg]20060127(012).jpgBeam dump.  This is a research machine, they don't actually do anything with the extracted beam other than measure it and then dispose of it in this large (and now radioactive) block of iron.
FFAG Tour [jpg]20060127(013).jpgI was a little concerned for my credit cards when I saw this sign but I assume it only applies when the machine is switched on, in which case people really shouldn't be going inside there anyway (let alone with scissors).
FFAG Tour [jpg]20060127(014).jpgI knew it wasn't switched on because this handy "FFAG ON" sign wasn't lit.
