The DAMIC-M experiment: Status and first results

The DAMIC-M (DArk Matter In CCDs at Modane) experiment employs thick, fully depleted silicon charged-coupled devices (CCDs) to search for dark matter particles with a target exposure of 1 kg-year. A novel skipper readout implemented in the CCDs provides single electron resolution through multiple non-destructive measurements of the individual pixel charge, pushing the detection threshold to the eV-scale. DAMIC-M will advance by several orders of magnitude the exploration of the dark matter particle hypothesis, in particular of candidates pertaining to the so-called “hidden sector.” A prototype, the Low Background Chamber (LBC), with 20g of low background Skipper CCDs, has been recently installed at Laboratoire Souterrain de Modane and is currently taking data. We will report the status of the DAMIC-M experiment and first results obtained with LBC commissioning data

Progress Report on Target Development

The present document is the D08 deliverable report of work package 1 (Target Development) from the MEGAPIE TEST project of the 5th European Framework Program. Deliverable D08 is the progress report on the activities performed within WP 1. The due date of this deliverable was the 5th month after the start of the EU project. This coincided with a technical status meeting of the MEGAPIE Initiative, that was held in March 2002 in Bologna (Italy). The content of the present document reflects the status of the MEGAPIE target development at that stage. It gives an overview of the Target Design, the related Design Support activities and the progress of the work done for the safety assessment and licensing of the target

Discussions on liquid bismuth target use as an alternative for astatine-211 production

International audienceAstatine-211 is an alpha emitter that has been identified as a good candidate for targeted alpha therapy. There is an increasing demand on this radionuclide. Very intense beam from linac being put in operation nowadays could be used to meet this demand. This document presents the design exploration of concepts of liquid bismuth targets dedicated to astatine-211 production. Three concepts are presented and analyzed: a capsule, a fluid loop and a windowless fluid loop. Structural and thermal sizing were performed using mechanical Finite Element models (ANSYS Workbench) and Computational Fluid Dynamic models (FLUENT). Production rates were assessed accordingly. Feasibility and expected performances are discussed in conclusion

Design and Supporting R&D of the XT-ADS Spallation Target

International audienceThe XT-ADS is an experimental accelerator-driven system (ADS) that is being developed within the framework of the European FP6 EUROTRANS project that runs from 2005 to 2009. In this paper the current level of the design of the XT-ADS spallation target and the status of corresponding R&D topics with respect to LBE handling, thermal-hydraulics and spallation product confinement are discussed

MEGAPIE target design and dimensioning

International audienceIn a collaborative effort, the MEGAwatt Pillot Experiment is an initiative to design, build, operate and decommission an exploratory liquid lead-bismuth spallation target for 1 MW of beam power, taking advantage of the existing spallation neutron facility and accelerator complex SINQ in PSI.After a successful engineering design review in November 2001, the technical review meeting in March 2002 and the first detailed design review in April 2002, the target design is now almost completed, the manufacturing phase is launched and the construction will start in April 2003 after the second detail design review and the ready for manufacturing review in March. The present contribution is not a detailed description of the target design, but gives an overview on some selected issues of relevance before going into manufacturing.This paper is based on the presentation held at the MEGAPIE Technical Review Meeting in Paris on March 18-19, 2003. The target heat exchanger and the electromagnetic pump system are presented in separate papers of the Meeting and will not be detailed in this paper
