Fast polycrystalline CdTe detectors for bunch-by-bunch luminosity monitoring in the LHC

The luminosity at the four interaction points of the Large Hadron Collider (LHC) must be continuously monitored in order to provide an adequate tool for the control and optimisation of beam parameters. Polycrystalline cadmium telluride (CdTe) detectors have previously been tested, showing their high potential to fulfil the requirements of luminosity measurement in the severe environment of the LHC interaction regions. Further, the large signal yield and the fast response time should allow bunch-by-bunch measurement of the luminosity at 40 MHz with high accuracy. Four luminosity monitors with two rows of five polycrystalline CdTe detectors each have been fabricated and will be installed at both sides of the low-luminosity interaction points ALICE and LHC-b. A detector housing was specially designed to meet the mechanical constraints in the LHC. A series of elementary CdTe detectors were fabricated and tested, of which 40 were selected for the luminosity monitors. A sensitivity of 104 electrons per minimum ionizing particle (MIP) and a pulse width better than 5 ns FWHM have been currently achieved

L’accompagnement du patient dans la pratique pharmaceutique : point sur les dispositifs formalisés

International audienceThe evolution of patient management has led the pharmacist to change gear and get closer to the patient. To better ensure these missions, several educational and support programs have emerged: "Advice", "consultations" and "pharmaceutical interviews", "shared medication report" or "therapeutic patient education", all these programs are intended "guarantee the best conditions for initiation, monitoring and compliance as well as evaluation of treatment", taking into account the wishes and needs of patients. Although these programs have similarities, there are significant differences (i.e. regulatory, functional, organisational, educational). The aim here is to clarify the various support programs in order to better know their fields of application and put them into practice
