Experts eye the eyes of the future
Two-day silicon photomultiplier workshop at DESY
New scintillator tiles for the calorimeter prototype. |
Sometimes detector projects that are still at a planning stage can tell detector projects that are already taking data what hardware to use. This is certainly the case when the R&D project has been using, trying and testing a technology that the 'old hand' is considering for its upgrade: a relatively new type of sensor called Silicon Photo Multiplier, or SiPM, developed in Russia. A meeting brought experts from all areas that use SiPMs together at DESY in Hamburg, Germany, for two days earlier this week.

S1 global update: tuner assembly successfully done at KEK

Following the successful cavity string work for superconducting acceleration cavities from Europe and Americas, a team of four scientists and engineers form INFN, Italy and Fermilab, US, arrived in Japan for the assembly work of the frequency tuners for S1-global work.
The voltage of the field changes with a certain frequency: a radio frequency (RF). For effective acceleration of charged particles in the superconducting acceleration cavity, controlling the RF resonance frequency in the cavity is crucial.

A trip to Washington
Today's issue features a Director's Corner from Mike Harrison, GDE Americas Regional Director.
Within shouting distance |
Pre-amble: One of the jobs of a Regional Director is to elicit support for the project beyond the traditional high-energy physics community. In this role Mike Harrison describes a recent trip to Washington to talk to the US Office of Science and Technology Policy (OSTP); the home of the Presidential Science Advisor.
So here I am, early in the morning preparing to leave. It's still dark outside and aargh, upon opening up the garage door I am greeted by fresh snow. By this winter's standards it's not a lot of snow, three to four inches (seven to ten centimetres), but sufficient to make getting the car out of my uphill sloping driveway problematic. If I need to shovel off the driveway then getting to the airport in time could prove interesting. A quick pause to down the last gulp of tea, wipe the ketchup stain off the tie, put out some birdseed into the feeder – they have a hard time in the snow – and we're off. Accelerating violently backwards out of the garage, I shoot up the driveway and skid sideways onto the road outside. No shoveling needed. Fortunately no-one is around at this ungodly time of day to witness this manoeuvre. I regain some semblance of car control and head out rather cautiously towards the airport. I hope the planes are flying. The web site indicates that all flights are operating but I have found to my cost previously that the web site isn't generally updated by this time of day.
