DESCRIPTION:Speakers: Vladimir Nazmov (Budker Institute of Nuclear Physics
 )\nIt is shown that the spatial resolution of an X-ray screen can be incre
 ased by forming structures like channels which are filled with a phosphor

 Tolochko\, Preliminary testing of microstructured imaging plates with impr
 oved spatial resolution. Nucl.Instr.Meth.Phys.Res.A448 (2000) 207-210]. It
  is established that the diameter of the channel is smaller\, the higher s
 patial resolution can be achieved. However\, the problem of filling of nar
 row channels is increasing. In the proposed method\, the phosphor has been
  mixed with the structured material SU-8 - resist and the patterning is ca
 rried out. Thus\, the need of filling of channels with a phosphor disappea
 rs. Due to the high penetration depth of hard X-rays into the materials du
 ring the patterning step\, regardless havy elements inside Gd2OS2 as a pho
 sphor\, the height of patterned microstructures can achieve tens or hundre
 ds of micrometers. The optical isolation of the patterned phosphor pillars
  is carried out by electroplating of nickel betweeen the pillars. The achi
 eved spatial resolution and the details of the manufacturing process heve 
 been discussed.\n\nhttps://indico.inp.nsk.su/event/3/contributions/1266/
