Facilities and Instrumentations

In the LUMiNaD laboratory we have built the first Ultrafast-TEM in Italy (and one of just a few in the world), where a femtosecond laser is coupled to a Transmission Electron Microscopy to provide simultaneous high temporal (femtoseconds) and high spatial (nanometers or below) resolutions.

SYSTEM SPECIFICATIONS

TEM:

• Multipurpose 200 kV JEOL JEM-2100 (HR) TEM with LaB6 electron source.

• IDES-UTEM conversion module for JEM 2100 with three optical accesses.

• Single-tilt and double-tilt sample holders.

• Liquid-He cryogenic sample holder (to be installed).

Electron detection:

• Scanning TEM detector for Bright-field and Dark-field imaging.

• Detector QUADRO (from DECTRIS): direct electron detector based on hybrid-pixel technology.

• 3 GHz transverse microwave RF cavity operated in TM-110 mode (from DrX Works).

Optical System:

• Amplified Infrared Femtosecond Laser PHAROS (from Light Conversion): pulse duration = 290 fs; wavelength = 1030 nm; maximum output power = 10 W; repetition rate = from single-shot to 600 KHz.

• Spatial Light Modulator (HOLOEYE Pluto) based on a liquid crystal display.
