多通道陣列式SDD系統

多通道陣列式SDD系統

多通道陣列式SDD系統最多支援七通道,可自由搭配Amptek SDD探測器,符合用戶之各種應用

  • 70 mm 2 FAST SDD,具有 C2 視窗(40 nm Si 3 N 4 ),用於檢測低至 Be K α線的 X 射線
  • 1 mm厚 70mm2 FAST SDD,高能量下的內在效率提高了 2 倍。
  • CdTe 偵測器效率高達 150 keV。
  • 可配置七個相同或任意組合的探測器,以更好地優化特定測量的感測器。
  • 相容於第三方多通道數位脈衝處理器。
  • 如果只有 1 個偵測器發生故障或窗戶破裂,不影響其餘探測器繼續正常運作,以便您可以繼續進行實驗。
  • 設計允許更快、更經濟地更換單一探測器

介紹:

XRA-700多通道 X-Ray光譜系統,配備七個具有低雜訊的前置放大器和高性能 X -Ray探測器,以及具有電源和冷卻的控制單元。XRA-700 可以配置七個相同的探測器,或多種不同種類的探測器,以滿足應用的需求

作為標準配置,系統配置有七個 70 mm 2 FAST SDD ® 偵測器,但其他選項包括:

  • 70 mm 2 FAST SDD,具有 C2 視窗(40 nm Si 3 N 4 ),用於檢測低至 Be K α線的 X 射線
  • 1 mm厚 70mm2 FAST SDD,高能量下的內在效率提高了 2 倍。
  • CdTe 偵測器效率高達 150 keV。
  • 可配置七個相同或任意組合的探測器,以更好地優化特定測量的感測器。
  • 相容於第三方多通道數位脈衝處理器。
  • 如果只有 1 個偵測器發生故障或窗戶破裂,不影響其餘探測器繼續正常運作,以便您可以繼續進行實驗。
  • 設計允許更快、更經濟地更換單一探測器
