Potential Italian contributions - PowerPoint Presentation

Slide1

Potential Italian contributions toWFI

L. Piro, IAPS-Romeon behalf of the Athena Italian team

Slide2

The rationaleThe

primary Italian contribution to mission elements is XIFU Other smaller contributions include participation to mirror and Ground Segment activities. This approach has been consistently presented to ASI and properly ackwnoledged by the agencyCredible approach for WFI contributions:

limited

and harmonized with

present commitments

on

XIFU.

For WFI we propose activities that

are carried out by the Italian consortium on XIFU and that can be – with a reasonable delta effort – developed for

WFI

BenefitBeneficial in terms of optimization of resources if (some of) instrument simulations activities are carried out for the WFI

as well. E.g.: Avoid duplication of same items: various components of L2 environment, GEANT model of the spacecraftSimilar design solutions for further reduction of the residual particle background (shields, soft particle diverter,…)

Analysis of Planck/SREM data

* Data courtesy of Dr. Paul Buehler, Andrea Zacchei and Luis Mendes

** (left) each bin is 1 day averaged. The decrease is consistent with the solar cycle that is going toward the max.

***(right) each bin is 50 s.

We analyzed the data from the Solar Radiation Environment Monitor onboard of Planck (SREM) in the period 2009-2013, since it is in the same orbit ATHENA+ will be placed.
