Milestones since 1999



The main paper on the STIC detector, for which I was the project leader, is published in Nuclear Instruments and Methods in 1999.


The first paper on photon events with missing energy is published by the DELPHI analysis team for which I am a convenor. Searches are made for SUSY particles, gravitons as predicted by extra dimension models and for compositness.


I present a mini-review of LEP searches for Supersymmetry, using events with photons and missing energy, on the ICHEP conference in Osaka, Japan in July 2000.


The latest DELPHI results are presented by me at LEP Fest 2000. One of the largest science symposiums ever held at CERN. And in the middle of the ALEPH Higgs "discovery"....


As the ATLAS radiation safety officer I am in charge of all activation studies in ATLAS which is summarized in a new website in 2001.


As the project leader for the muon shielding project I present a new shielding design in the ATLAS overview week in Clermond-Ferrand in June 2002. I am able to reduce the shielding with more than a 1000 tonnes without worsening the background in a significant way.


The Skoda Steel company cast the 100 tonnes heavy forward shielding pieces in 2003 that we designed in my shielding group.


The main paper on single photon and two photon analysis in DELPHI is submitted by me in 2004 and it is published in 2005.


The ATLAS Radiation Taskforce report is published in January 2005. This book deals with radiation background, shielding design, Monte Carlo calculations, activation and detector response to radiation.


I propose a new much cheaper and simpler design of the shielding inside the center of the endcap toroid magnets in July 2005. It is made of cast iron instead of expensive copper but it does not disturb the magnetic field in the magnet or increase the background in the muon detectors.


We finish building the first disk shielding in July 2006. It is used to support and protect the first forward muon station in ATLAS, the so-called "small wheel".


A new simplified design of the LUCID detector is presented by me in the ATLAS week in February 2007.


The disk shielding and the small muon wheel is installed by my shielding team in February 2008 after several years of planning, design and manufacturing of the special lifting equipment that was needed.


The LUCID detector is installed in ATLAS in July 2008.


The large ATLAS detector paper is published in the Journal of Instrumentation in August 2008. I was one of the editors of the paper and I wrote the chapter about background, shielding and activation.


The ATLAS control room on the 10th of September 2008 when a LHC beam is detected for the first time in ATLAS.


The single photon spectrum produced by me in DELPHI ends up on the cover of the Europhysics Journal in February 2009.


The last piece of the 836 tonne heavy forward shielding is installed in ATLAS in August of 2009. This means that the ATLAS shielding project has been succesfully completed.


The ATLAS luminosity group for which I am a co-convener publishes the first luminosity paper in the Europhysics Journal in April of 2011.


I present the ATLAS luminosity measurements in the 2011 Europhysics Conference on High-Energy Physics (EPS-HEP 2011).


Proceedings


The ATLAS luminosity group for which I am a co-convener publishes the second luminosity paper in the Europhysics Journal in August of 2013.


The LUCID II detector for which I am the project leader is installed in ATLAS in October 2014.


The LUCID II group publishes its first detector paper in the Journal of Instrumentation in May of 2016.


The ATLAS luminosity group for which I am a co-convener publishes the third luminosity paper in the Europhysics Journal in December of 2016.


I present the LUCID II detector at the 2017 Particles & Nuclei Conference in Beijing (PANIC 2017).


Proceedings


The LUCID II group publishes its second detector paper in the Journal of Instrumentation in July of 2016.


LHCC publishes the LUCID III design report in October of 2021 after the detector has been approved by ATLAS as a small upgrade project for the high-luminosity LHC.


I present the LUCID III detector at the 2022 ICHEP Conference in Bologna.


Proceedings
Video


The ATLAS luminosity group publishes the fourth luminosity paper in the Europhysics Journal in October of 2023.
