“…Different techniques can lead to uncertainty between measurements. However, we assume that the uncertainty induced by the various techniques and probing wavelengths [12] is consistent with the dosimetry of the different installations. Moreover, the statistical uncertainty induced by a low number of deposit-inducing events also produces uncertainty in the measurement.…”

“…For this class of dosimeter, the maximum dose will be fixed by the dynamic range of the RIA measurements (today dynamic range of 50 dB are possible). In the case of distributed measurements, the spatial resolution will be limited by the length needed to reach 5 mdB while the sensing length will be, at the first order, fixed by the dynamic range of the reflectometer [12].…”

“…As an example, CERN deployed it along their facilities or accelerators to monitor with OTDR the TID distribution [10], [11]. Finally, a very interesting property of those fibers is that their χ coefficient around 1550 nm appears to be almost independent on the type of particles; it is therefore possible to measure TID deposited by a variety of individual species or in mixed environments, as shown for X-ray and -ray photons [4], [5], [12] atmospheric neutrons [13], protons [4] or at the CHARM facility [14]. This clearly opens the way for the implementation of such sensors in very diverse environments for a variety of applications.…”

We present a simulation-assisted methodology for the design of point or distributed fiber dosimeters exploiting the linear dependence of the infrared radiation-induced attenuation of a single-mode phosphosilicate optical fiber. We demonstrate by comparing Monte Carlo simulations and experiments at different irradiation facilities (X-rays, -rays, protons and atmospheric neutrons) that the sensitivity coefficient of this fiber is independent on the nature of particles and on dose rate, at least up to total ionizing doses in the order of 500 Gy. Our simulations allow us to simulate the dose deposited in the fiber core (and then the Radiation Induced Attenuation (RIA) levels) for the different classes of particles (photons, electrons, neutrons, protons and heavy ions) and for different energy ranges. From this data, and knowing the environments of targeted applications for the fiber optic dosimeters, we can discuss the different designs and achievable performance using this fiber. Examples are discussed with space applications, atmospheric balloon experiments and fusion-devoted facilities.

“…The RIA at 1550 nm of this optical fiber depends linearly on the total ionizing dose (TID), up to at least 500 Gy [1,17]. It was proven to be resistant to the influence of dose rate, between 1 µGy/s and 10 Gy/s [1,2,17], together with its weak recovery after irradiation. To give the reader an order of magnitude about these dose rate values, equipment sent to space missions generally encounters dose rates between a few µGy/s to a few mGy/s, depending on the orbit and amount of shielding in place.…”

“…In its most simple configuration, the input pulse duration is the key factor in determining the spatial resolution achievable with this technique [8]. With modern OTDRs working in the infrared spectrum at telecommunication wavelengths, the spatial resolution is around 50 cm, using a pulse duration around 5 ns [2,9]. As an example, this technique is usually employed over several tens of km of optical fiber to precisely individuate the position of any breaks or bending losses that are present along the telecom line.…”

The combination of an ultra-low-loss optical fiber sensitive to ionizing radiation and an optical time domain reflectometer (OTDR) is investigated to explore the feasibility of a single-ended distributed radiation detector. The peculiarity of the tested fiber resides in its regenerative high radiation-induced attenuation (RIA) response in the infrared spectrum (1310 nm), which returns to a low value once the irradiation has ended, combined to its sensitivity, highly increasing with the dose rate. In this work, only some sections of the fiber line were irradiated with 100 kV X-rays at room temperature, to prove the spatially resolved radiation detection capabilities of the system. The transient RIA response of the fiber was characterized at different pre-irradiation doses. A pre-irradiation treatment was shown to stabilize the optical fiber response, improving its RIA vs. dose rate linearity and repeatability. This improved response, in terms of radiation quantification, comes at the cost of a lower detection threshold. This work lays the bases for a distributed radiation detector, with some capabilities in dose rate evaluation.
