STATEMENT
The aim of Interdipartimental Crystal Research & Analysis Center (ICRYS), formed by researchers of the three Departments SIMAU, DIISM and DICEA of the Università Politecnica delle Marche (UNIVPM), is to give Scientific and Technical support to Research & Development activities of Universities, Public and Private Research centers and Manifacturing Enterprises working in the field of crystal analysis, characterization and production.
The Center provides experimental and analytical support both in the field of theoretical analysis and in that of industrial and technological applications. Development of new technological processes, novel measurement methods, design of innovative software and training of researchers (in particular PhD and master students) and technical personnel are also encompassed within the Center mission.
 
COMPETENCES
The researchers associated with the Center have interdisciplinary competences which span from Theoretical and Experimental Physics to Continuum and Applied Mechanics, Applied Mathematics, Numerical Analysis and experimental and measurement methods. They are accordingly able, by such a multidisciplinary approach, to completely characterize crystals from micro to macroscopic scale passing through mesoscopic scale models, both theoretically and experimentally.
Therefore, the Centre can characterize crystallographic structure, chemical composition and electrical, optical and mechanical properties of both large-  and micro-scale crystals.
 
FACILITIES
The Center researchers have access to the following facilities and instruments of the three participating Departments.
a) Structural Analysis:
  • X-Ray Diffractometers
  • Laser Vibrometer and Pulsed Laser
  • Ultrasound and Acoustic Probes
  • Transmission Electron Microscope (TEM)
  • High-Resolution  Scanning Electron Microscope (HRSEM)
b) Photoelastic and Optical Analysis:
  • Sodium Diffused Light Polariscope
  • He-Ne Laser-polariscope
  • Optical table with 6 d.o.f.  motorized positioner
  • Spectrometer (UV-VIS-IR) with optical fiber
  • Digital multimeter
  • Peltier cells and controller
  • Minithermostat
c) Mechanical Analysis:
  • Single point, tangential, scanning laser vibrometers
  • Ultrasounds and acoustic resonance method
  • Optical scanners
  • Controlled climatic chamber
  • Force and pressure transducers
  • Controlled testing machine
d) Support services
  • 3D addictive manufacturing units (Polymer and metal printing)
 
EXPERIMENTAL ACTIVITIES
The Center experimental activities allow for a complete characterization of crystals, as well as other scintillating systems (i.e. powders, fibers, etc.), both in terms of crystallographic parameters and in composition by means of Microscopy and Diffractometry instruments and techniques.
Optical and dielectric properties are studied by means of photoelastic techniques whereas mechanical properties are obtained with vibrometric techniques and mechanical test, both destructive and non-destructive.
 
THEORETICAL ANALYSIS
The researcher associated to the Centre have the experience in Solid State Physics and Continuum Mechanics which is necessary to obtain mesoscopic scale models which bridge the microscopic world of the crystalline cell with the macroscopic one of the bulk industrial crystal. This is a mandatory approach when one deal with “innovative” materials like most of the industrial crystals are. These models allow for parametric analysis and are reliable benchmarks for any numerical analysis and experimental test design.
 
INTERNATIONAL RESEARCH COMMITEMENT
Besides the industrial and applied researches, Center members are involved in many international researches activities. On the top of the list there are:
  • The Crystal Clear Collaboration (CERN R&D 18) a CERN-based research network whose scope is the study and the understanding of existing and new scintillator properties as well as the technological transfert of the research results;
  • The PANDA collaboration which is associated to one of the key experiments at the Facility for Antiproton and Ion Research (FAIR) which is under construction and currently being built on the area of the GSI in Darmstadt, Germany and which uses PWO scintillating crystals as main detectors.
