Paula Collins

The design and construction of experiments for HEP typically involve thousands of people, stretch over decades, and have to respect choices which keep the detectors affordable and acceptable to the collaboration and funding agencies.  In this inaugural lecture we will discuss some of the basic guiding principles of detector design, focusing in particular on semiconductor based vertex detectors for colliders, and using as a particular example the design, construction and performance of the LHCb experiment and its vertex detector.  We will show that along the way individuals have been able to make a profound impact on the course of detector design and technology selection.  As examples we will discuss the investigations of radiation damage effects in silicon detectors for the LHC, the design and re-optimisation of the LHCb experiment, and the cross disciplinary links between medical and High Energy Physics Instrumentation.    We will have a brief look at the requirements for future experiments, which will surely be heavily drawing on the technologies which will be discussed throughout this Barcelona Technoweek.

Paula Collins is a CERN physicist, currently leading the LHCb VELO (Vertex Detector) project as it prepares the Upgrade installation for Run 3.  In the past she has worked on the original LHCb VELO construction, as well as carrying out silicon detector research for the RD50 collaboration.  Before joining LHCb she worked on the DELPHI experiment, leading the DELPHI Silicon Tracker project which installed strips and pixels for the LEP2 running.  Before joining CERN she worked on various aspects of the DELPHI detector both as a student at the University of Oxford and as a Royal Society Fellow, affiliated with the University of Oxford.

Erik Heijne

Erik H.M. Heijne studied physics at the University of Amsterdam, where as a student he collaborated
in projects on storage of hydrogen/deuterium in palladium (1969) and on quantum effects in thin silicon
films (1970). He came in 1973 to CERN in Geneva, to work on silicon detectors for the monitoring of
the neutrino beams. On this subject he earned his PhD in 1983 at the University of Amsterdam. In 1980
he demonstrated the silicon microstrip detector in particle physics, which opened new ways for characterizing particles with charm and beauty quarks. This earned him the 2017 European Physical Society Prize in High Energy Physics, with Robert Klanner and Gerhard Lutz, who implemented this instrument in the CERN NA11 experiment. After a stay in Leuven (B) 1984-85 he started with Pierre Jarron in 1986 the microelectronics design group at CERN. An important initiative was the development of an imager-like silicon particle detector for parallel, high rate position and time determination of multiple simultaneous particles, at first named 'micropattern detector' but now widely known as silicon pixel detector. Together with Michael Campbell at CERN, in the framework of the LAA project and the RD19 collaboration, the first complete demonstration of a hybrid pixel detector was given in 1991, in a heavy ion experiment in the Omega spectrometer. Around 1995 he introduced at CERN the ideas for radiation hardness of chips by design and layout, which eventually facilitated the widespread use of custom-designed monolithic CMOS chips in the LHC collider experiments. His interests center on the applications of advanced CMOS technology and various sensor materials for imaging of particle interactions and other physics phenomena involving radiation. He is a Fellow of the IEEE and besides the EPS-HEP 2017 Prize already mentioned, he received in 1999 the Merit Award of the IEEE Nuclear and Plasma Sciences Society.
