Predlagani izum se nanaša tudi na postopek izdelave omenjenega detektorja.The present invention relates to a detector for high-efficiency detection of photons, in particular to high-efficiency detection of photons of gamma energies. The present invention also relates to a method of manufacturing said detector.
Detektorji uvodoma navedene vrste so znani in se jih uporablja na primer na področju sledilnikov nabitih delcev v eksperimentih ob pospeševalnikih. Omenjeni detektorji obsegajo silicijev senzor s priključnim območjem za n blazinic. Od vsakokratne blazinice teče priključni vodnik, na primer tanek aluminijast vodnik, ki je razporejen v območju nad vsakokratno blazinico. Senzor na osnovi tovrstne rešitve ima znatno debelino, kar ima za posledico nizko prostorsko in časovno ločljivost detekcije, nizko polnilno razmerje in s tem slab izkoristek detekcije fotonov.The detectors of the type mentioned above are known and are used, for example, in the field of particulate matter trackers in accelerator experiments. These detectors comprise a silicon sensor with an attachment area for n pads. A connecting conductor runs from each pad, for example, a thin aluminum conductor arranged in the area above each pad. A sensor based on this kind of solution has a considerable thickness, which results in low spatial and temporal resolution of detection, low charge ratio, and thus poor photon detection efficiency.

Detektor za visoko učinkovito detekcijo fotonov obsega nosilni ploskovni element 1, ki je v danem primeru večplastno tiskano vezje, pri čemer je omenjeni ploskovni element 1 zasnovan na način, da obsega osrednji togi odsek 2 in gibka odseka 3, 4, ki sta omenjenemu togemu odseku 2 na po sebi znan način priključena z njegove vsakokratne vzdolžne strani. Omenjeni togi odsek 2 je s svoje vsakokratne ploske strani zasnovan z nizom v rastru razporejenih in medsebojno izolacijsko ločenih kontaktov 2', ki so na po sebi znan način povezani z omenjenim večplastnim tiskanim vezjem 1. Omenjena izolacijska ločitev omenjenih kontaktov 2' je predvidena s pomočjo mostiča med dvema sosednjima kontaktoma 2', pri čemer so omenjeni mostiči na po sebi znan način zasnovani iz foto spajkalne kritine.The high-efficiency photon detection detector comprises a supporting planar element 1, which is optionally a multilayer printed circuit, said planar element 1 being designed to comprise a central rigid section 2 and a flexible section 3, 4, both of which are rigid sections 2 in a manner known per se connected from its respective longitudinal side. Said rigid section 2, on its respective flat side, is designed by a series of rasterly arranged and mutually separated contacts 2 ', which are in a known manner connected to said multilayer circuit board 1. Said isolation separation of said contacts 2' is provided by bridges between two adjacent contacts 2 ', said bridges being, in a known manner, designed from a photo-solder coating.
Omenjenemu togemu odseku 2 večplastnega tiskanega vezja 1 je z njegove vsakokratne proste ploske strani priključen senzor 5 fotonov, v danem izvedbenem primeru silicijev senzor z nizom v rastru razporejenih blazinic 5' za detekcijo žarkov gama. Omenjeni niz blazinic 5' na omenjenem senzorju 5 je rastrsko razporejen na način, da se ujema z omenjenim v rastru razporejenim nizom omenjenih kontaktov 2' na togem odseku 2. Omenjena priključitev vsakokratnega senzorja 5 togemu odseku 2 je zasnovana s pomočjo niza v rastru razporejenih in medsebojno izoliranih otokov 6 adhezijskega sredstva med togim odsekom 2 in vsakokratnim senzorjem 5, pri čemer se omenjena rastrska razporeditev ujema z rastrsko razporeditvijo omenjenih blazinic 5' na senzorju 5 oz.Said rigid section 2 of the multilayer circuit board 1 is provided with a photon sensor 5 from its respective free, flat face, in the present case a silicon sensor with a array of 5 'gamma ray spaced pads. Said set of pads 5 'on said sensor 5 is rasterly arranged in such a way that it matches the rasterly arranged series of said contacts 2' on rigid section 2. Said connection of each sensor 5 to rigid section 2 is designed by means of a series of rasterly arranged and the isolation islands 6 of the adhesive agent between the rigid section 2 and the respective sensor 5, said raster arrangement being matched to the raster arrangement of said pads 5 'on the sensor 5 or.
omenjenih kontaktov 2' na togem odseku 2. Po predlaganem izumu je predvideno, da je omenjeno adhezijsko sredstvo izbrano kot električno prevodno termoplastično lepilo. Zaradi nizkega modula elastičnosti termoplastičnega lepila je s tem omogočeno zanesljivo spajanje elementov z različnimi temperaturnimi koeficienti raztezka.of said contacts 2 'in rigid section 2. According to the present invention, it is provided that said adhesive agent is selected as an electrically conductive thermoplastic adhesive. Due to the low modulus of elasticity of thermoplastic adhesive, this enables reliable bonding of elements with different temperature elongation coefficients.
Detektor za visoko učinkovito detekcijo fotonov po izumu se izdela na način, da se na vsakokratni omenjeni kontakt 2' iz niza v rastru razporejenih kontaktov omenjenega togega odseka 2 nanese otok 6 adhezijskega sredstva, v danem izvedbenem primeru termoplastičnega lepila. Omenjeni nanos se opravi na primer s pomočjo ustrezne maske ali zaslona ali po postopku pipetiranja ali podobno. Ko se omenjeno adhezijsko sredstvo posuši, se na omenjeni togi odsek 2, ki je opremljen z otoki 6, namesti omenjeni senzor 5, tako da se raster razporeditve blazinic 5' ujema z rastrom otokov 6. Ko sta obe ploski strani togega odseka 2 opremljeni z otoki 6 in senzorjem 5, se ta sklop stisne, prednostno pri temperaturi, ki je višja od temperature okolice. Pri predstavljenem izvedbenem primeru je znašal tlak, s katerim se je omenjeni sklop stisnilo, med 1,5 in 2,5 bar, medtem ko je temperatura, pri kateri se je izvajalo stiskanje, znašala v območju med 150 in 200 °C. Čas stiskanja je znašal približno 60 minut. Na tak način se dobi izvrstno vertikalno povezavo med togim odsekom 2 oz. njegovimi kontakti 2' in senzorjem 5 oz. nizom njegovih blazinic 5', pri čemer otoki 6 ostanejo medsebojno še vedno izolirani.The detector for highly efficient photon detection according to the invention is made in such a way that at each said contact 2 ' from a series of arranged contacts 2 of said rigid section 2 is applied an island 6 of the adhesive, in a given embodiment of thermoplastic adhesive. For example, said application is by means of a suitable mask or screen, or by pipetting or the like. When said adhesive agent dries, a sensor 5 is mounted on said rigid section 2, which is provided with islands 6, so that the raster arrangement of the pads 5 'is aligned with the raster of islands 6. When both planar sides of the rigid section 2 are provided with islands 6 and sensor 5, this assembly is compressed, preferably at a temperature higher than ambient temperature. In the embodiment shown, the pressure by which said assembly was compressed was between 1.5 and 2.5 bar, while the temperature at which the compression was carried out ranged from 150 to 200 ° C. The compression time was approximately 60 minutes. In this way an excellent vertical connection is obtained between a rigid section of 2 or. its contacts 2 'and the sensor 5 oz. a series of its pads 5 ', leaving the islands 6 still isolated from each other.
