HELIOS – Hardness Evaluation with Laser for Investigation Of SEE
With nearly 50% of CMOS COTS components sensitive to destructive Single-Event Effects in space radiation environments, Pulsed Laser testing provides a fast and cost-effective alternative to heavy-ion accelerators for component pre-selection, a method TRAD has mastered over 10+ years, with 100+ devices tested.
Two Laser available on the HELIOS Facility:
A Single Photon Absorption Laser (SPA):
- Wavelength: 1064 nm
- Pulses’s duration < 700 ps
- Repetition rate from single-shot up to 50 kHz
- Tunable pulse energy from few pJ to several nJ
- Laser diameter: 1.8 μm (x100) up to 8 μm (x10)
The SPA Laser is adapted for silicon device’s SEE screening, with a Single Photon Absorption (SPA) process.
A Two Photon Absorption Laser (TPA):
- Wavelength: 400-2400 nm
- Pulses’s duration < 370 fs
- Repetition rate from single-shot up to 100 kHz
- Tunable pulse energy from few pJ to several nJ
- Laser diameter: 1.8 μm (x100) up to 8 μm (x10)
The TPA Laser is wavelength tuneable and can be used for research purposes and for testing Wide Band Gap components, using Two Photon Absorption (TPA) processes.
VASCO –Californium (Cf252) Source
This low-activity source (a few μCi) is used in a vacuum chamber equipped with the same connections as the accelerators used for heavy ion tests.
This is used to prepare SEE tests and notably, to optimize the time spent on accelerators at external facilities.
UV means
Our UV exposure means can be used to irradiate samples under vacuum in accordance with the ECSS-Q-ST-70-06C norm. The available exposure area is 6 x 6 cm. This test means accelerates the exposure time up to a factor of 15, while respecting the number of ESH (Equivalent Sun Hour).
Thermal cycling
We own several thermal cycling chambers, under vacuum and inert atmosphere, compliant with the ECSS-Q-ST-70-04C standard. The accessible temperature ranges are:
-under vacuum: -190 ° / + 190 ° C or -180 ° / + 200 ° C
-under inert atmosphere: -180 ° / + 400 ° C
All of our thermal cycling chambers enable to implement in-situ electrical measurements.
SWIPI – Solar Wind Proton Irradiator
We own a solar wind experimental simulator that exposes samples to low-energy protons (energy range from 300 eV to 5 keV) under vacuum. The exposure can be carried out at high or low temperatures, in the range of -180 ° / +200 ° C, with the possibility of in-situ electrical measurements.
VEISPA – Vacuum Electron Irradiation facility for Spatialization
Based on a LINAC-type accelerator, this test means can be used to irradiate samples under on electron beam of 1 to 4 MeV under vacuum. The available exposure area is 30 x 30 cm. The tests can be carried out at high or low temperatures, in the range -150 ° / + 200 ° C, with the possibility of in-situ electrical measurements.
