  2. XACT facility at INAF-OAPA • Facility for the development, test and calibration of instrumentation for soft X-ray Astronomy. • Transmissivity, reflectivity, and quantum efficiency measurements in the soft X-ray band (0.1-20 keV) and UV. • Test and calibration in full imaging mode of moderate angular resolution (PSF > 10” FWHM), and small diameter (< 40 cm) grazing incidence X-ray optics. • Test and calibration of X-ray cryogenic detectors. [Collura et al. 1994(8), 1996(14); Barbera et al., 1994(7), Barbera et al. 2000(62)]

  9. Participation in the development and calibration of experiments for soft X-ray Astronomy • Chandra HRC: development and calibration of the UV/Ion shields, X-ray quantum efficiency of microchannel plates, end to end test; • Newton-XMM EPIC: development and calibration of the thin and medium filters, monitoring ageing effects of back-up filters; • JET-X CCD: development and calibration of the filters; • Solar-B XRT: development and calibration of the filters, reflectivity measurements of flat mirror samples.

  10. Chandra HRC: development of the UV/Ion shields • Investigation of different plastic materials • Simulation of the expected out of band rejection • Vibrational and acoustic tests • Baseline design • Calibration plan

  11. Chandra HRC: UV transmission measurements of the UV/Ion shields at the XACT facility Aluminum oxidation and interferences New filter design: Polyimide instead of Lexan, and single layer of aluminum (impact on Chandra ACIS, Newton-XMM EPIC, and JET-X).

  12. Chandra HRC: X-ray transmission measurements of the UV/Ion shields at the XACT facility • X-ray Source • Transmis. Grating Monoch. • GFPC + MCP detectors

  13. Chandra HRC: X-ray transmission measurements of the UV/Ion shields at Bessy Synchrotron • X-ray Transmission modeling • XANES and EXAFS

  14. Chandra HRC: Measurement of the UV/Visible refractive index of Polyimide • UV/Visible transmission measurements • of monolayer films • Parametric model of the extinction • coefficient K

  15. Newton-XMM EPIC: Filter development and calibration plan Newton-XMM EPIC: UV filter transmission measurements • Out of band rejection Newton-XMM EPIC: Synchrotron X-ray filter transmission measurements • X-ray Transmission modeling • XANES and EXAFS

  16. Newton-XMM EPIC: X-ray shadowgraphs of thin and medium filters at the XACT facility • GFPC+MCP detectors • Mosaic of 9 images

  17. Newton-XMM EPIC: Monitoring ageing effects of the thin and medium filters July 1997 July 2002 • Not modeled as an increase of aluminum oxidation • Possible explanations: Polyimide, Al surface roughness • No significant impact on the EPIC calibration

  18. JET-X CCD: Filter development and testing

  19. SOLAR-B XRT: Focal Plane Filter calibration • X_ray shadowgraphs • X-ray transmission measurements and modeling SOLAR-B XRT: Entrance Filters calibration • X-ray transmission measurements and modeling of • small filter samples SOLAR-B XRT: telescope calibration • Reflectivity measurements of flat mirror samples vs. • energy and angle of incidence. [Ongoing calibration program]

  20. Simbol-X: Coperte Termiche • Studio dei requirements termici (Alcatel Alenia) • Baseline design (ottico - meccanico) (OAPA+Luxel+Alcatel Alenia) • Misure su witness samples (OAPA) • Design finale (OAPA+Luxel+Alcatel Alenia) • Realizzazione (Alcatel Alenia + Luxel (?)) • Test meccanici (Alcatel Alenia) • Calibrazione (OAPA) • Protoni lenti (resistenza + stopping pwr) TBD

  21. Development of grazing incidence X-ray Optics • Plastic foils from common industrial applications • High surface smoothness by a combination of stretching • and rolling in higly polished rollers • Plastic is very light, elastic, cheap, has strong affinity to • coating • Plastic foils replicate the figure of the mandrel but not • the smoothness. Expensive superpolished mandrels not • required

  22. Shaping and coating the foils • Single and multilayer coating on large size foils before shaping • Vacuum hold-down mandrels to form cylindrical or conical shells [Schnopper et al.,1999(30)]

  23. Holding the foils • Foils hold inside grooves of the supporting wheels • Epoxy cured while foils are still inside the mandrel [Schnopper et al., 2001(42)]

  24. Full X-ray imaging tests at XACT [Barbera et al., 2001(64)]

  25. FWHM ~ 10” HPD ~ 2’ [Schnopper et al., 2002, Proc. SPIE 4851, in press]

  26. Detector Source Simbol-X: Un’idea per il test delle ottiche • Realizzazione di 2 ottiche identiche • Montaggio sullo stesso asse con i fuochi in direzioni opposte • Sorgente X puntiforme in un fuoco, rivelatore nell’altro fuoco • La PSF misurata è in prima approssimazione la somma in quadratura delle due PSF • Possibilità di migliorare ulteriormente l’informazione con scambi, rotazioni, masking
