Scintillation characteristics have been studied for detectors of charged particles and low-energy gamma-quanta
produced on the basis of Ticor single crystals.
PACS: 29.40.Mc
1. INTRODUCTION
Scintillators based on Ticor (Al2O3:Ti) are known as
materials for detectors of short-range ionizing radiation
that are distinguished by their high chemical, thermal
and radiation stability. The present work was aimed at
studies of scintillation characteristics of both single
crystalline and polycrystalline scintillators based on
Ticor for detection of α-particles from 238Pu and γ-
quanta from 241Am.
2. DETECTORS AND EXPERIMENT
Studies have been carried out of single crystalline
samples in the geometry of rectangular plates, discs and
truncated pyramids, as well as of detectors based on
composition materials comprising polycrystalline Ticor
scintillators and organic binders.
Scintillation characteristics of detectors were
measured using a spectrometric circuit that included a
charge-sensitive preamplifier of PU-G-1K-2 type, a
linear amplifier of BUS2-97 type and a multi-channel
pulse amplitude analyzer of AI-1024-95 type. As
photoreceiver, we used an R 1307 Hamamatsu PMT
with photocathode diameter of 3”. The signal
integration constant (RC) was 8...12 μs.
For excitation of the detectors, we used α-radiation
sources of OSAI type (А=104 Bq) and γ-radiation
sources of OSGI type (А=105 Bq). A collimator with
one or two openings was placed between the detector
and α-radiation source.
We have compared characteristics of a single
crystalline detector shaped as a rectangular truncated
pyramid, dimensions of the basements 25х8 mm and
15х5 mm, height – 30 mm, another single crystalline
detector shaped as a rectangular plate 10х10х1 mm, and
a polycrystalline composite detector (disc-shaped, ∅
40х5 mm).
Fig.1 shows the pulse amplitude spectrum obtained
from the rectangular Ticor plate under excitation by α-
particles from 238Pu (Еα=5,5 МeV) using a collimator
with one opening.

Fig.1. Pulse amplitude spectrum from Ticor-based
single crystalline detector, dimensions 10х10х1 mm,
under excitation by a-particles from 238Pu
The energy resolution Rα value at this energy was
16.5%, and the α/β–ratio for the crystal was 0.64.
The α/β–ratio depends, finally, on the irradiation
geometry, light collection coefficient and pulse
characteristics of the spectrometer used. Thus, under α-
irradiation of the upper base of the truncated pyramid
the α/β–ratio was 0.34, while for the side surfaces this
value was 0.46. At the same time, with the rectangular
plate at RC = 8 μs the α/β–ratio value was 0.64, and at
RC=12.8 μs – 0.75.
In this relationship, of substantial interest were also
the composite detectors based on Ticor. In Fig.2,
characteristics are shown for such a detector under
irradiation by α-particles from 238Pu and γ-quanta from
241Am (Eγ=59.6 keV).
The values of Rα= 48-49% at Rγ =96.5%, that is
quite satisfactory for composite detectors of this type.
According to the calculated and experimental data
given in [1], The paths of fission products of heavy
nuclei 233,235U, 239Pu with mass numbers from 131 to 136
were from 3.095 to 3.60 mg/cm2. Data obtained in [2]
on the sensitivity of Ticor scintillation single crystals to
ion radiation show a possibility to use these crystals for
detection of fission products.
