Stephen Brooks 🦆Our collaboration with Stony Brook Radiation Oncology on Dejan Trbojevic's medical FFA accelerator design has now produced a paper: "Developing Bragg-peak FLASH proton irradiator using permanent magnet synchrotron" in the Journal of Radiosurgery & SBRT. The link is provided below, although not everyone outside medicine has a subscription to this! #physics #accelerators
To approximate the expected number of multi-way collisions, I used a simple physical model where nuclei are spheres with density 2.5e17 kg/m^3 and they interact if the centre of one goes within another. Then in the code below I work out a "volume fraction" of the focal ellipsoid that is filled and an "area fraction" that is filled in 2D projection seen from the side with largest area.

Depending on how stable the intermediate products are, you can also get chained collisions within the bunch diameter. #physics #accelerators
3-way collisions are usually only seen inside the cores of stars and, if there are super-heavy elements yet to be found, this may be a way of making them.

universeinthelab_en🏆🌍 New #worldrecord at GSI/FAIR in Darmstadt!
192 discovered #nuclearisomers at our institute. With 143 of these discoveries, Dr. Ivan Kojouharov (GSI/FAIR) is at the top of the global rankings of co-discoverers.
Only possible due to our unique combination of #accelerators and measuring instruments.
Many thanks to Professor Michael Thoennessen from Michigan State University, USA, who compiled the statistics!

Last week I looked inside Brookhaven National Laboratory's tandem Van de Graaff accelerator. The platform in the middle is called the terminal and can be raised to 15 million volts while surrounded by insulating SF6 gas (unusual to see an accelerator large enough to climb inside!) I wanted to see if there was room for an ultra-cold ion source, which could create nanometre-scale ion beams once accelerated by the Tandem. #physics #accelerators
Basin-hopping optimisation of a particle beam transfer line with six different energies in it. #physics #accelerators Something like this might be required for the 22GeV CEBAF energy upgrade at Jefferson Lab, to join the arcs to the linac where all the beams are in the same pipe.

Doing a first assembly and fit test of ion trap's next configuration. This time, the electron beam is going through the trap and can be switched on and off rapidly via deflection electrodes and a small hole. The blue plastic is modelling the Micro-Channel Plate that is still in storage vacuum. #physics #accelerators
Simulation of a long bunch breaking up into solitons in the BNL booster synchrotron. #accelerators #physics This required setting focussing magnets to much weaker than normal and starting with a dense, high space-charge bunch. Doing this experiment in practice could be a precursor to crystalline beams, as when Coulomb crystals are put in place of the solitons here, they heat up by less than 1 Kelvin/second.
