CAMEA is a novel instrument concept, thus the performance has not been explored. Furthermore it is a complex instrument using many analyser arrays in a wide angular range. The performance of the instrument has been studied by use of three approaches: McSta ...
This paper characterizes the effective beams, the effective beam window functions and the associated errors for the Planck High Frequency Instrument (HFI) detectors. The effective beam is the angular response including the effect of the optics, detectors, ...
We discuss the methods employed to photometrically calibrate the data acquired by the Low Frequency Instrument on Planck. Our calibration is based on a combination of the orbital dipole plus the solar dipole, caused respectively by the motion of the Planck ...
Le zonage en urbanisme, véhiculé à travers le monde, s’hybride avec les modalités locales de l’utilisation du sol. Au Japon et en Suisse, le zonage est reconnu pour être l’instrument le plus puissant de l’organisation spatiale. La différence réside dans la ...
We propose the construction of a highly innovative spectrometer – CAMEA – offering Continuous Angular and Multiple Energy Analysis. Combining indirect time-of flight with multiple consecutive analyser arrays, this instrument will provide massive flux on th ...
During the design of CAMEA extensive simulations and cinematic calculations were performed to explore the waste parameter space. These have led to a far better understanding of the instrument performance as well as new ideas to improve the instrument. Many ...
CAMEA is a new instrument concept so it is possible that the construction could or maintenance of the instrument would be hampered by technical details. In order to prevent this a technical predesign have been performed. This is not a final technical solut ...
We here describe the result of simulations of 15 generic neutron instruments for the long-pulsed European Spallation Source. All instruments have been simulated for 20 different settings of the source time structure, corresponding to pulse lengths between ...

A new Raman lidar for unattended, round-the-clock measurement of vertical water vapor profiles for operational use by the MeteoSwiss has been developed during the past years by the Swiss Federal Institute of Technology, Lausanne. The lidar uses narrow fiel ...
