Postdoctoral position at LLR and LAL on imaging calorimetry and machine learning
The Laboratoire Leprince Ringuet (LLR) and the Laboratoire de l'Accélérateur Linéaire (LAL) offer a postdoctoral position which has been granted by the excellence cluster 'P2IO' of laboratories in the South of Paris.
The groups play a leading role in the development of highly granular calorimeters as required e.g. for precision measurements at a future linear electron positron collider at the TeV scale. The work will comprise the analysis of real and simulated data recorded with the prototypes of the CALICE collaboration. The study seeks to optimise the two particle separation in the granular calorimeters. This goal is addressed by applying and developing advanced machine learning algorithms which extract characteristic features of hadronic showers. The development of new algorithms require a decomposition of the different stages of a shower. This will bring new insight into the physics of hadronic cascades. In the long term the results should lead to an optimisation of the reconstruction algorithms for detectors at a future LC. It is also intrinsic to the nature of the position to establish synergies with other fields of science.
The described work is situated at the interface between particle and detector physics and applied mathematics and the postdoctoral fellow will work together with leading experts in both fields.
Candidates are required to have Ph.D. in physics, computer science, mathematics, or engineering by date of appointment. Research experience in experimental high energy physics or a related field and data analysis (for physicists) or research experience in applied statistics or machine learning (for computer scientists) is required. The successful candidate is expected to have demonstrated skills in data analysis and a good knowledge of C++ . Experience in the development of tracking algorithms are desirable but not requested.
The position is available for a period of two years starting on 1st October 2012. Salary and benefits will commensurate with the ones of a Level-2 Young Researcher (CR2) at CNRS (National Center for Scientific Research), approximately 2500 Euros/month according to the experience.
The job offer is oriented towards candidates which are less than two years after the end of the PhD thesis. In case of interest please send a one page letter of motivation, your cv and the name and addresses of three referees until 10 June 2012 to Dr. Vincent Boudry (email@example.com), Dr. Balazs Kegl (firstname.lastname@example.org) and Dr. Roman Pöschl (email@example.com). Please be ready for an interview in the second half of June.

Detector R&Ds and physics analyses mostly related to the International Linear Collider (ILC)
The High Energy Physics lab. at Tohoku University invites applicants for a postdoctoral research associate position to work on detector R&Ds and physics analyses mostly related to the international linear collider (ILC). The Tohoku University group is one of the leading groups working on ILC, Belle, and Belle II, and productive interactions among these efforts are expected. The position is supported by the JSPS program 'grant-in-aid for specially promoted research: a global research and development program of a state-of-the-art detector system for the ILC'. The term is until the end of fiscal year (March 31) with possible extensions until the end of the grant; namely, March 31, 2017.
The salary depends on the qualifications of the applicant, and ranges roughly from 3.6 million yen to 4.2 million yen per year. The successful candidate is expected to take leading roles in the effort, and good skills in detector hardware and physics analyses are essential.
Ph.D. degree in physics at the start of the term is required.
A cover letter stating your intent, CV, and two letters of recommendation are to be sent to Hitoshi Yamamoto by e-mail (email@example.com) or by postal mail (Physics Department, Tohoku University, 6-3 Aza-Aoba Aramaki Aoba-ku Sendai, Japan, postal code 980-8578). Applications should be received by September 1, 2011.

Test, analysis and integration of an imaging Silicon-Tungsten ECAL
The Laboratoire Leprince Ringuet (LLR) and the Laboratoire de l'Accélérateur Linéaire (LAL) in France, laboratories of the IN2P3 within the CNRS, are searching for a post-doctoral researcher. The research entails detector development for a detector to be operated at a future linear electron-positron collider. The groups are heavily involved in the R&D of a Silicon-Tungsten electromagnetic calorimeter. The successful candidate is expected to contribute in particular to the development and testing of the Silicon wafer technology and its associated front-end electronics of a large scale prototype.
The analysis of data taken on site as well as during future beam test campaigns is also an integral part of the tasks. In this context, the work will give the opportunity to contribute to physics studies by optimising so called particle flow algorithms, an event reconstruction technique crucial to achieve the envisaged precision at a future linear collider. This work may involve the application of modern pattern recognition algorithms which can also be applied in other fields of science.Candidate profile
The position is reserved to non-French citizens.
Candidates are required to have a Ph.D. in experimental high physics or a related field by date of appointment. Interest and skills in data analysis and hardware development are premises for a successful application.
