PhD, Project Leader

High-Purity Germanium Production For Ultimate Precision Gamma-Spectroscopy

Page 2: Geros suv2016

High-Purity Germanium (HPGe): Unique Semiconducting Material for Gamma and X-ray Detection

• Lowest band gap = best energy resolution

• No competitors in complex radionuclide identification (mixtures, low activity)

• Application domains: – Radioecology– Atomic energy– Nuclear security– Cargo scanning– Science

I. Ultra-deep purification & single crystal growth

II. Detector block manufacturing (+n/p layers, contacts, cryostat)

III. End-user device assembling(+electronics, high-voltage supply, etc.)

•Extreme purity required: |nD – nA| < 1010 cm-3

•Global market: $170–280 million/year•Crystal production segment: $60–120 million/year•Raw material ~1 500 $/kg, HPGe ~15 000 $/kg

Our niche

Page 4: Geros suv2016

Present-day Limitations

Technology• Multiple Zone-Refining:

– Time/resource consuming– Safety issues

• Czochralski pulling:– Risk of cracking– Bigger size is hardly

achievable

Market• Umicore EOM – the only

crystal supplier• ORTEC + Canberra = oligopoly

Consequences• Overpricing • 100% import share • Long delivery & repair• Possible ban due to sanctions• New application development

is hindered

Our Tech Innovations

Key Ingredients• Rotating Container method:

Czochralski + Bridgman• Low temperature gradients:

precise thermal control

Advantages• Minimized contact with walls• Enhanced purification efficiency• Low H2 consumption

• Thermal stress decrease

Potentialities• Superior crystal size• Single setup

Current status• Prototype implementation &

small-scale production start• Investments required: 300 k$• Period: 3 years
