Ugo (polarimeter)

Spider bụ nnwale nke balloon emebere ka ọ chọọ ebili mmiri ndọda mbụ nke etinyere na mbara igwe igwe igwe (CMB). Ịtụ ike nke mgbama a na-etinye oke na tiori onu oriri

Nnyocha Spider na-anọdụ n'ụgbọelu ahụ tupu ụgbọ elu mbụ ya n'elu Antarctica.

Ngwá ọrụ Spider nwere telivishọn isii nwere ogo isii nK a na-eme ka ọ dị jụụ na okpomọkụ Helium (4 K) nke na-ahụ na frequency nke 100 GHz, 150 GHz, na 280 GHz (nke kwekọrọ na wavelengths nke 3 mm, 2 mm, na 1.1 mm).        A na-ejikọta onyokomita ọ bụla na bolometer (TES) nke na-emetụta polarisation nke na-eme ka ọ jụọ oyi ruo 300 mK.  Spider bụ ngwá ọrụ mbụ iji gosipụta ihe nchọpụta TES nke oge na-agbanwe agbanwe na gburugburu ebe obibi. 'oge ụgbọ elu mbụ n'elu Antarctica na 2015, Spider bụ ngwá ọrụ microwave kachasị dị nro eme.

Ihe mgbaru ọsọ sayensị bụ isi gụnyere:

1. njirimara nke akụkụ na-enweghị curl nke CMB polarization na nnukwu ihe ọ̀tụ̀tụ̀
2. ịchọ akara nke inflationary gravitational waves na polarization CMB
3. njirimara nke polarization njirimara nke ikuku sitere na Milky Way Galaxy anyị

Ụgbọ elu balloon mbụ nke nnwale a malitere na Jenụwarị 2015 site na McMurdo Station, Antarctica, na nkwado sitere na NASA's Columbia Scientific Balloon Facility. Ụgbọ elu Balloon Ogologo Ogologo a were ihe dị ka ụbọchị iri na asaa, na-esepụta ihe dị ka 10% nke mbara igwe. Ihe data sitere na ụgbọ elu a weputara onyonyo nrịbama-na-mkpọtụ nke ike na akara polarization nke Cosmic Microwave Background, na ọkwa mkpọtụ 3--5 ugboro dị ala karịa ụgbọ elu Planck dị n'otu mpaghara nke mbara igwe, na-ebute oke nha. nke CMB na ụzarị mbara ihu Galactic, yana oke siri ike na oke tensor-to-scalar cosmological. Ụgbọ elu ndị ọzọ akwadoro maka oge na-aga n'ihu na-eme ka nkwalite na mgbanwe dị na teliskop modular, mkpuchi ugboro ugboro na omimi.
