Other Irradiation Facilities

As IRADETS company, IRADETS has usage permits and priorities in the irradiation facilities accredited for many space programs thanks to its long years of experience in this field, international collaborations and close collaborations. These irradiation facilities;

ALMANYA – Fraunhofer, FEP, Darmstad, for low/medium energy high intensity electron irradiations (0.6- 1.5 MeV) 

Thanks to the electromechanical system we developed, solar cells, optical elements, kapton metamaryel and composite material etc. are tested according to ECSS.

Technicial Specifications: It complies with ECSS / ESA standards, with protons at 0.04 MeV to 50 MeV and electrons at energies from 0.6 MeV to 30 MeV, irradiation parameters and performances with a flux of approximately 1013 particles / (cm2.s).

Advantages: Testing in nitrogen atmosphere, temperature control of irradiated products, wide and uniform irradiation area (80 cm x 12 cm), flux control.

İTALYA – Electron-LINAC of Terni Hospital, electron beam with energies from 4 to 20 MeV

With the simulation software we have developed, it is possible to calculate and control all the important parameters of the electron accelerators (e-Linac) used in radiotherapy (beam size, distribution, energy, flow etc.). The simulation program, which includes all the elements of an e-linac, including the title part, is the optical materials, meta-materials, composite materials, real-time performance can be tested according to the ECSS standard, as well as any imaging, transponder or particle/radiation detectors to be sent to space. It is also possible to see how their performance has changed.

Technicial Specifications: Electrons with energy between 4 and 20 MeV have 5.107 (electron / cm2s) flux at a distance of 100 cm.

Advantages: With detailed drawings of the head part, it is possible to irradiate different target materials in accordance with ESA / JEDEC / MIL / ASTM standards with any e-Linac’s 4-20 MeV energy range.

Customers: INAF (Istituto Nazionale di Astrofisica), ESA

iTALYA – INFN-LNS (Catania) at superconducting cyclotron for SEE and DD tests with heavy ions and protons

Laboratori Nazionali del Sud (LNS) is one of INFN’s four national laboratories. The research activity is mainly working on the structure and properties of the atomic nucleus, in collaboration with researchers from many countries.

There are two particle accelerators in the LNS: 15 MV Tandem Van De Graaff used for the first experiments in the early 80s and a K800 Superconductive Cyclotron in full operation since 1996.

For the SEE test and proton (several MeV to 60 MeV) irradiation, MAPRAD has developed a new dosimetry system based on silicon photomultipliers (SIPM). The four SIPMs are in a fixed position around DUT, and the fifth SUTM can move in front of DUT. The system provides real-time flux and beam spot homogeneity. The irradiation device provides many advantages by working in the air.

The sites below are other irradiation facilities that we have access to and we perform various tests;

1. UCL-Université Catholique de Louvain (Louvain La Neuve, Belgium) and RADEF-Finland for SEE and DD testing in vacuum with heavy ions.

– In UCL-LIF (Light Ion Facility) to test the DUT behavior at very low surface LET values 

– In UCL-HIF (Heavy Ion Facility) for surface LET values up to 60 MeV/mg/cm2)

– In RADEF are available two cocktails with surface LET values from around 1 to about 60 MeV/mg/cm2

– Both facilities provide beam uniformity, ion fluxes and ranges in silicon are in accordance with ECSS/ESA standard.

2. CNA Seville and HZDR Dresden for proton  irradiations

– In these sites we can prepare, execute and assist in all phases your irradiation campaign with  protons from 0.04 MeV to 50 MeV and electrons from 0.6 MeV to 30 MeV, with particle fluxes from single particle to about 1013 particles/(cm2.s). The beam parameters and performances are compliant with ECSS/ESA standards.

3. ESTEC/ESA, TAEA-SANAEM (Ankara, Turkey), ENEA-Calliope (Rome, Italy), Univerista’ di Palermo, ), CNR-ISOF , UCL-Université Catholique de Louvain (Louvain La Neuve, Belgium) facilities for  60Co gamma ray source for TID irradiation;  high-dose, ELDRS (Enhanced Low Dose Rate Sensitivity) and industrial dose rates

– MAPRAD has executed many test in all in these Co-60 gamma irradiation sites. The available Dose rates are from ELDRS dose rate values (0.5-to-10 mrad(Si)/s)  up to industrial dose rate values of up to 10 kGY/h and to TID values of 15 MGy.

– We can irradiate a single IC component die as well as an Euro-pallet size of about 500 kg. 

4- Frascati Neutron Generator (FNG-ENEA) for neutrons of 14 MeV (2.5 MeV also is possible)

– The FNG facility can provide accurately-measured fast neutron fluxes up to 5∙109 n/(cm2.s). It produces up to 1∙1011 n/s of 14 MeV neutrons in continuous or pulsed mode (minimum pulse length 6 μs.)

– FNG can also produce 2.5 MeV neutrons by using deuterated targets by means of the D(d,n)3He fusion reaction. The maximum neutron flux of 5∙107 n/(cm2.s) in continuous or pulsed mode.
