\u00dastav experiment\u00e1lnej fyziky SAV v. v. i., je zapojen\u00fd do medzin\u00e1rodnej spolupr\u00e1ce na pr\u00edprave misie PBR (POEMMA-Balloon with Radio). Pre hlavn\u00fd teleskop boli vyvinut\u00e9 \u0161tyri vysokocitliv\u00e9 detektory EMON, ktor\u00e9 bud\u00fa zabezpe\u010dova\u0165 kontrolu sveteln\u00fdch podmienok po\u010das letu stratosf\u00e9rick\u00e9ho bal\u00f3nu programu NASA.<\/b><\/p>\n

\u201ePripravovan\u00e1 vesm\u00edrna misia POEMMA (Probe Of Extreme Multi-Messenger Astrophysics) m\u00e1 za cie\u013e pozorova\u0165 z orbity Zeme tie najenergetickej\u0161ie \u010dastice, ktor\u00e9 vo vesm\u00edre existuj\u00fa. D\u00f4le\u017eit\u00fdm krokom pre t\u00fato misiu je technologick\u00fd test kritick\u00fdch zariaden\u00ed, ktor\u00fd bude vykonan\u00fd po\u010das stratosf\u00e9rick\u00e9ho letu misie PBR. Je pre n\u00e1s ve\u013ekou c\u0165ou participova\u0165 na tejto unik\u00e1tnej misii, ktor\u00e1 m\u00e1 potenci\u00e1l sprostredkova\u0165 prelomov\u00e9 objavy,\u201d<\/i>\u00a0uviedol kozmick\u00fd fyzik \u0160imon Mackovjak.<\/p>\n

Pripravovan\u00e1 misia PBR by mala \u0161tartova\u0165 u\u017e o rok, v marci 2027, z bal\u00f3novej z\u00e1kladne Wanaka, Nov\u00fd Z\u00e9land. P\u00f4jde o let stratosf\u00e9rick\u00e9ho bal\u00f3na, prev\u00e1dzkovan\u00fd agent\u00farou NASA, ktor\u00fd m\u00e1 vo v\u00fd\u0161ke 30 km zotrva\u0165 pribli\u017ene 100 dn\u00ed. Po\u010das nich bude pomocou vysokocitliv\u00e9ho optick\u00e9ho teleskopu a r\u00e1diovej ant\u00e9ny detegova\u0165 energetick\u00e9 sp\u0155\u0161ky v atmosf\u00e9re vyvolan\u00e9 \u010dasticami kozmick\u00e9ho \u017eiarenia s ultravysok\u00fdmi energiami. Na palube misie PBR bud\u00fa aj detektory vyvinut\u00e9 v Ko\u0161iciach na Oddelen\u00ed kozmickej fyziky \u00daEF SAV, v. v. i. Konkr\u00e9tne ide o detektory EMON, ktor\u00e9 bud\u00fa monitorova\u0165 sveteln\u00e9 podmienky v hlavnom optickom teleskope.<\/p>\n

\u201eHlavn\u00e9 po\u017eiadavky, ktor\u00e9 sme mali od kolegov z USA, boli spo\u013eahlivos\u0165 a miniaturiz\u00e1cia na\u0161ich pr\u00edstrojov. Preto sme detektory EMON navrhli tak, aby boli schopn\u00e9 odol\u00e1va\u0165 extr\u00e9mnym podmienkam (teplote do -50 \u00b0C a tlaku na \u00farovni tis\u00edciny atmosf\u00e9rick\u00e9ho tlaku) a z\u00e1rove\u0148, aby mohli by\u0165 vhodne umiestnen\u00e9 v hlavnom teleskope. Podarilo sa n\u00e1m tak vytvori\u0165 rie\u0161enie, ktor\u00e9 kolegovia z kolabor\u00e1cie ve\u013emi ocenili,\u201d\u00a0<\/i>kon\u0161tatovali Igor Strh\u00e1rsk\u00fd a J\u00e1n Bal\u00e1\u017e, ktor\u00ed meracie pr\u00edstroje navrhli, skon\u0161truovali a otestovali v laborat\u00f3riu na Oddelen\u00ed kozmickej fyziky \u00daEF SAV.<\/p>\n

EMON deteguje sveteln\u00e9 podmienky s vysokou citlivos\u0165ou na \u00farovni 50 pW\/cm\u00b2. Funguje samostatne v\u010faka vlastn\u00e9mu softv\u00e9ru a automatick\u00e9mu vyhrievaniu. Minul\u00fd t\u00fd\u017ede\u0148 boli zaslan\u00e9 \u0161tyri kusy do Neapola (Taliansko) na integr\u00e1ciu do fluorescen\u010dn\u00e9ho teleskopu misie PBR. V najbli\u017e\u0161\u00edch mesiacoch bud\u00fa prebieha\u0165 testy celej aparat\u00fary a koncom roka sa m\u00e1 realizova\u0165 transport na Nov\u00fd Z\u00e9land.<\/p>\n
