2 2 ************************************************************************************ 3. Experimental particle physics at LHC: track-based alignment of CMS silicon tracker The CMS experiment is a large general-purpose particle physics experiment at the LHC. Its innermost part, the tracker, consists of about independent silicon sensors. To ensure precise and unbiased physics measurements, positions of sensors need to be determined and monitored with particle tracks (track-based alignment). The summer trainee will participate in alignment studies of the CMS tracker. Physics student (or applied/engineering physics); three years of studies (or more); interest to proactively work in a truly international team of researchers. Knowledge of C++. Experience with python and Unix is an important advantage. Also some introductory level knowledge of particle physics is a benefit (or as agreed) Tapio Lampén, supervisor Katri Lassila-Perini, supervisor Tel Tel tapio.lampen@cern.ch, katri.lassila-perini@cern.ch ************************************************************************************ 4. Silicon pixel detector characterization The summer student will characterize detector modules that will be installed to the upgraded CMS pixel detector. In addition, the student participates into developing and fine tuning the test benches in the laboratory, which requires basic knowledge of object oriented programming.

3 3 Jaakko Härkönen, supervisor Tel ************************************************************************************ 5. Research and development for instrumentation in nuclear physics at ISOLDE Project (1): The ISOLDE facility at CERN is dedicated to research on exotic nuclei, i.e. nuclei with short lifetimes and small production rates. The low-intensity beams are not visible with standard ion beam diagnostics, such as Faraday cups, so to estimate their intensity ISOLDE relies on detecting their decay. The setup used for this purpose is a tape station, where the ions are implanted into a thin metallic tape and they are then moved by some cm towards beta and gamma detectors. In this project the student will save ISOLDE by ensuring that the tape station is in a good shape for the next experimental campaign. The student will test all elements (tape-moving system, detectors, and controls) with and without ion beam. The student will also calibrate the detectors with beta and gamma sources, so that the system is ready when the protons are again delivered to ISOLDE. Project (2): Isolde Yield Database. The Isolde Yield database is an important access point for physicists to conceive and plan experiments at ISOLDE. It centralizes information on the availability and intensities of the different radioactive ion beams. The present version lacks some important functionality, such as yield intensity plots and some of the user interfaces to update the database information. The student will be in charge of looking through the database structure and existing functions, and to develop the missing elements. Project (1): Third year physics student with basic courses in physics and interest to work in a laboratory environment with an international team of researchers. Ideally familiar with beta and gamma sources and detectors. No specific software knowledge is required. Project (2):

Engineering design of the RF structures for CLIC Position for a mechanical engineering/applied physicist/materials engineer/electrical engineer summer trainee is available in the framework of the radiofrequency (RF) structure development for the Compact Linear Collider (CLIC). The ongoing CLIC study is developing the accelerator technology for a future linear collider. The student will be integrated in the accelerating structure development team who is working on the core element and one of the most critical parts of the entire accelerator project. Resistance of materials to high electric fields and the related breakdown phenomenon are one of the main limitations for the performance of high gradient accelerators as CLIC. Two instruments for studying DC electrical breakdown in vacuum are available in the laboratory at CERN. These instruments can be used for the measurements of breakdown field, breakdown rate, and electron field emission and are coupled with other diagnostics tools relative to plasma arcs. The student will perform such experiments as a function of the applied external field, temperature of the system, etc, as well as in depth data analysis of the conducted experiments. The aim of the work is to further assess the onset and the nature of plasma arcs on various materials and their respective surfaces within a frame of ongoing R&D efforts. The working tools will be MatLab and LabView. The work will be closely linked the development of the accelerating structure for CLIC and hence the student will participate in the dedicated meetings including technical presentations. The exact job description will be adjusted to the interests and competences of the student.
