ATLAS Luminosity Upgrade for the Super-LHC: Working on planning the new Inner Detector for ATLAS -
Preliminary work by TJF on ATLAS upgrade ID off-barrel services

The Current ATLAS SCT Barrel Detector at the LHC at CERN
work started in 1998 and finished in 2007/2008 and the detector is now inaccessible, installed at the heart of the ATLAS detector at the LHC:

Work was carried out using the ATLAS SCT Barrel Detector models and prototypes constructed at UCL for testing assembly procedures, mechanical designs, cable routing etc; working closely with RAL, Oxford and Geneva University. This now includes ATLAS SCT barrel detector Assembly and Integration taking place at CERN, Geneva (2005, 2006, 2007).

DESY (Hamburg)

The ZEUS CENTRAL TRACKING DETECTOR at HERA, DESY

The Central Tracking Detector was a wire chamber in the form of a cylinder around the beam pipe, outside a small vertex detector.
I worked on the CTD project from start to finish, at Oxford, RAL and DESY. The prototype called Centaur was constructed at Oxford and tested at RAL then the final CTD was constructed at Oxford, tested and shipped to Hamburg where it underwent extensive testing in the JADE Hall before being installed in the ZEUS Hall at HERA.

The Discovery of Neutral Currents in 1973

I joined the Bubble Chamber Group at UCL early in 1972 during a most exciting stage in High Energy Physics.
The aim was to discover neutral currents using the heavy-liquid bubble chamber called Gargamelle at CERN, Geneva.
The Gargamelle Collaboration was founded four years earlier in 1968 - that's 40 years ago!! and consisted of groups from Aachen, Brussels, CERN, Ecole Polytechnique, Milan, Orsay and UCL.
In 1972, with data arriving from CERN in the form of thousands of photos on rolls if film, everyone had to work around the clock to record and measure the neutrino interactions - neutrino or antineutrino beam in CF3BR. We were joined, usually for a night shift, by physicists from Oxford, who lacked our state-of-the- art scanning and measuring equipment at the time.
The discovery of weak neutral currents so long ago leads, by way of the later discovery of the W and Z, to the LHC where the Higgs, the last part of the electroweak Standard Model awaits.......
