Focussing & Chromatic Correction focussing element

Focussing & Chromatic Correction higher dispersion glass SiO 2 amorphous fused silica

Focussing & Chromatic Correction higher dispersion glass two boundary surfaces to turn correction mostly angle-independent different curvatures required curvature is compromise internal reflection angle independent of light never leaves dense optical medium  good for phase space

Focussing disc DIRC focal plane of focussing lightguide with rectangular photon detector pixels focal plane coord. [mm] lightguide number lightguide “200mm” LiF SiO 2

Light Generation radiator thickness –number of photons transparency –wide wavelength range (eV) – high statistics material dispersion –either narrow w. band –or correction required

Particle Path Straggling  x  (  ) x standard deviation of  x angle information of upstream tracking is 0.57 off  (  ) x Cherenkov ring Cherenkov ring image is blurred by 0.38  (  ) x  reduce radiator thickness, reduce X 0 2 sigma envelopes   K fused silica, thickness??

Light Propagation 10 mrad individual angle variations:  = Pixel / sqrt(N) 1 mrad about reflections length 400mm, =400nm  d=1mm (approximately) d Fresnel Zone rough surface causing path length differences and phase shifts

Expansion Volume advantageous peripheral tracks create local high photon density the further outward, the more radial the light paths increasing particle angle rim proximity performance does drop towards disc perimeter outer limit of acceptance coverage

Focussing Lightguides short focal plane 50mm ~1mm pixels needed optical errors exist thicker plate a problem focal plane 100mm pixel width 2-3mm benign optics thicker plate ok

Light Detection detector geometry magnetic field (~1T) photon rate (MHz/pixel) light cumulative dose radiation dose photon detection is a problem still to be solved

Focussing disc DIRC focussing is better than 1mm over the entire line chosen as focal plane light stays completely within medium all total reflection compact design all solid material flat focal plane radiation-hard “glass” RMS surface roughness at most several Ångström LiF for dispersion correction has smaller |dn/d | than SiO 2 focal plane coord. [mm] lightguide number lightguide “200mm” rectangular pixel shape LiF SiO 2

Momentum Thresholds fused silica n=1.47 aerogel n=1.05 K K p p  total internal reflection limit n=1.47 K p  

Detector Performance z_from_target[mm]= 2000 disc_radius[mm]= 1100 disc_thickness[mm]= 10 nzero[1/mm]= 14 (0.4eV) LiF corrector plate radiation_length[mm]= 126 B [Tesla] = 2 momentum[GeV/c]= 5 beta= 0.98 n_lightguides= 192 lightguidewidth= 25 lightguidelength= 65 (from apex) lightguide focal plane = [32,80] lightguide pixel size= 1 simulation example with  2 fit analysis short lightguide 125mm, focal plane 48mm p 2 -p 1 = 4 x (  1 /2 +  2 /2)

In brief fused silica radiator disc, around the rim: –LiF plates for dispersion correction –internally reflecting focussing lightguides one-dimensional imaging DIRC radiator with very good RMS roughness required perfect edges (as in the BaBar DIRC) not needed number-of-pixels ~ p 4 stringent requirements for photon detectors two alternative designs, one DIRC, one RICH two examples of material tests working on Cerenkov detectors for PANDA: Edinburgh, GSI, Erlangen, Gießen, Dubna, Jülich, Vienna, Cracow, Glasgow

Time-of-Propagation design M. Düren, M. Ehrenfried, S. Lu, R. Schmidt, P. Schönmeier single photon resolution ~30-50ps needed [deg] t [ps] relevant for ToP idea: reflect some photons  several path lengths mirrors reflective hole

Proximity Focussing design design variation with mirror and the expansion volume upstream radiator placed closer to EMC C 6 F 14 CsI + GEM suggestion Lars Schmitt: combine tracking and PID

Material Test (1) Testing transmission and total internal reflection of a fused silica sample (G. Schepers and C. Schwarz, GSI)

Material Test (2) Irradiation test at KVI Schott LLF1 HT glass sample (B. Seitz, M. Hoek, Glasgow)
