CMUXE Research: HEIGHTS ITMC IMPACT LPP UI-LPP DPP Ion Channel

IMPACT & PRIHSM Labs

IMPACT (The Interaction of Materials with Particles and Components Testing experimental facility) PRIHSM (Particle Radiation Interaction with Hard and Soft Matter) facilities have been designed to study in-situ dynamic heterogeneous surfaces at the nano-scale exposed to varied environments that modify surface and interface properties. These facilities are used to investigate to investigate radiation-induced modification of materials and surfaces with applications to fusion science, nanotechnology and detector development.The philosophy behind experiments in IMPACT/PRIHSM relies heavily on its ability to provide a wide array of characterization techniques and conditions that properly simulate complex environments.  The IMPACT/PRIHSM experiment achieves this by atomic-scale characterization of the evolution of elemental, chemical, and thermodynamic states of ultra-thin film surface and interfaces using complementary surface-sensitive characterization techniques.

In-situ techniques used in the IMPACT:

  1. Dynamic X-ray Photoelectron Spectroscopy (XPS)
  2. Dynamic Auger Electron Spectroscopy (AES)
  3. EUV(13.5-nm) Photoelectron Spectroscopy (EUPS)
  4. Ultraviolet Photoelectron Spectroscopy (UPS)
  5. EUV reflectometry (EUVR)
  6. Low-Energy Ion Scattering Spectroscopy (LEISS)
  7. Direct Recoil Spectroscopy
  8. Mass Spectrometry
  9. Secondary Electron Spectroscopy (SES)
  10. QCM
