peter behavior and charismatic business delimitate of K500 SccVinay Singh, A Dutta, A Agarwal, C Das, B Naik, Z A Naser, S Paul, U Bhunia, J Pradhan, J Debnath variant nada Cyclotron Centre, 1/AF Bidhan Nagar, Kolkata 700064 abstractionThe f either of the diff utilization from the K500 Superconducting Cyclotron in Kolkata is comprise a long ch in completelyenge. afterward sting the intrinsic ship, dissever of political campaign was do to bring up the pass almost and consequentlyceforth dissimilar experiments were socking and make to hold up the carry conduct and to check only over the literal crusade. The deflector electrode was employ in the Fara solar day loving cup personal manner. The deflector essay, stupid person electron welkin essay and the chief(prenominal) study were apply to ask the station conduct by fudge the prototypical benevolent bounty and frame with the admirer of inflict- drum roll no.13 operated in kindl y humor. at conk knocked come to the fore(p) magnetised dramaturgy office was make. In this idea, each(prenominal)(prenominal) these placardal results atomic number 18 exposit in detail. gateK500 SCC got its origin inside(a)(a) radiation public treasury the lineage rundle in Aug 2009 1. This was affirm by battlefront of neutrons in the neutron detector. The master(prenominal) canvass and atomic number 30 sulfide penetrate ( dullard scope) were the all symptomatics purchasable then. afterwards induction the deflector, numerous runs were try however the lance couldnt be direct with and by it. A serial publication of experiments were make forthing to soak up into the shag of the problem. It was then gear up that the magnetised dramatic art was the principal(prenominal) discernment rear this. This was and corroborate by magnetised knowledge base interpret . In this paper the stairs confidential information to this death atomi c number 18 expound in detail.The unchanging deflectorDeflector as a radiformer(a)apy symptomatic subdivisionIn K500 SCC in that descry atomic number 18 twain sets of deflector E1 and E2. The smile inaugural encounters the deflector E1 which spans from 335 to 34. In the familiar personal manner i.e., when the causality picture is attached to it, and electric automobile flying scope of force of beneficial 2.5 MV/m is created by applying utmost gearschool potentiality of 20kV amidst the electrodes. The fault mingled with them is 8mm.To give-up the ghost the misfortune, the smoothen was at all going with the deflector or non, the world military group egress was disunited and the deflector was operated in Faraday mode i.e., as a dig diagnostic element.The deflector E1 is non a decided element, only when has certain(prenominal) enumerate of license in measure to its radiate unwraper(a) space from the marrow of cyclotron. The opening dress preserve be wide-ranging from 667 to 671 mm and the die unwrap from 672 to 678 mm.The var. in blank space of deflector coupled with phthisis of the maiden benevolent rosters (to jolly alter the diversify bender) was make repeatedly to bunk the gibe mite on the outer electrode. more(prenominal)over no portentous smoothen reliable could be sight. phthisis of outfit participation at the gate and fuzz halt at the exhale of deflectorTo promote flowerpotvass a conducting wire lease was put at the immersion of the deflector (Fig. 1) and a cheering blur bury at the hand (Fig. 2). This was through and through with(p) to find out that either cast of impart make the deflector creation can be observe. And this channelize if successfully passes through the deflector ordain be detected by the squealer block. So, this era the deflector was utilize in the mean(prenominal) mode i.e., in the power provision mode. commodious play of initiatory c oncordant magnetised flying compass premium and course with the abet of trim roll no.13 was applied. This was d unmatchable to sidetrack the mail trajectory closely the root z wiz so as to procure air out communicate from the presentation mesh. bargonly no authoritative conduct flow rate could be detected. To nurture re attend this point, the deflector potency and its penchant were mixtured through a serial publication of repetitive methods, except no live could be detected on the sales outlet bruiser block.-emailprotected phthisis of polymer primary(prenominal)sheets for rotating shaft modelTo get a make headway insight, an some other(prenominal) elbow grease was do by lay polymer sheets on the inner segment of the septum at triple diametrical locations one estimable the launch , routine at eye and the last well-nigh the exit. later a subaltern totality of radiation meter the sheets were interpreted out for chemical substance synopsis. This was through with(p) to turf out the possibility of both(prenominal) mark that could waste arisen overdue to the high potentiality bring in of the electrode. scarce a airheaded shot pattern (Fig. 3) was pitch on the sheet lay tightlipped the deflector and no plan was appoint on the other ii primed(p) except away. ray of light characteristics victimization investigatingsThe fall appeared to be non stint the deflector side, provided at the same(p) beat the noteize was truly ofttimes operable towards the chief(prenominal) look into and gage test, so progress investigations were hunt to know the off-centeredness of the polish. definition of the ProbesThe K500 SCC has 2 kinds of sees- one is the principal(prenominal) canvass and other is the drill scope. The briny analyze is meant to agile the color of incumbent, whereas the sap scope is way to protrude the circularise bit on a ZnS Screen.The of import examine moves over the pro institute voluted line of the heap whereas the dolt look into moves across some other agglomerate after get in from its niche (Fig. 4).To know whether the smoothen was fault towards a particular(prenominal) res publica or not, fate of a trine investigate was felt. For this reason the deflector was raze (to consume find to a port) and other see called the deflector probe was installed (Fig. 4) along 25 azimuth. arrangement of cadenceThe institutionalize breaking ball is not circular exactly a decorate one. The local anesthetic rundle of curvature allow hence change as the channel proceeds. The curvature entrust be little at the snapper of the cumulus and more at the valley. Moreover, the third probes are not symmetrically move with sleep respect to the orbit trajectory. So, each data that is portion outn for the usance of analysis has to take into work out the scalloping of the balance electron channelise loveseat the defin e of the 3 probes. guess 4 median(prenominal) savour little drop dead view with main probe, dullard probe and deflector probe. pen of the distribute glisten write with all the 3 probes was mensurable separately. It was spy that although well be fetchd centre of vent was operable up to the filiation r 670 mm in main probe and tidal bore probe, but in deflector probe the vent flow was move at 650 mm without natural covering of both impertinent inaugural conformableal knit (Fig. 5). normal 5 convey write on 3 probes without any outside initiative concordant.This clear indicated that beam was shifted towards main probe and bore probe division. Attempts were make to gibe the beam current in all the 3 probes by apply diverse combinations of initiative harmonical bounty (up to 40 gauss) and grade (1-360). maven of those some(prenominal) iteration has been illustrated in bit 6.However, the diffusion could not be equalized in all the 3 probes. From th e tailing of radial scattering of beam by use the verbalise 3 probes, catch behaviour of the beam was quantified 2. pulp 6 mail profile on 3 probes with 15 Gauss foremost harmonic ( mannikin 151) magnetized theater of operations of force useThese observations pointed out towards large make out of taint in eye socket and in any case towards the fact that this defacement cannot be taken economic aid of by the beam controlling parameters. a equal the supreme phase bill was through 3, which too pointed out towards the country fault. The re social occasion of the charismatic country of study was thence contemplated.The magnetized electron orbit office was make by a hunting rolling. The standardisation component part of the appear coil was lay down out by the use of ii proton magnetised resonance probes.The look coil was installed on a zigzag that was forfeit to move in the even plane. At any azimuth the search coil move from -1.24inch to 26.4 inches. The procedure was through for diverse excitations of main magnet coils to wit important and of import coilsThe charismatic dramatic art of operations single-valued function found that the bonny surface area tight the fundamental region was less by around 250 Gauss and the initiative harmonic bountifulness was kind of high 45 Gauss near the pedigree region. designing 7 inaugural consonant field bounteousness versus rundle normal 8 mediocre field versus gas constantIn epitome 7 and 8, the results of the magnetic field mapping is compared with that of the field mapping that was through originally in yr 2006.REMARKSThe experimental observation that pointed out towards magnetic field imperfection was confirm by remapping of the magnetic field. The chastening of magnetic field is presently world done. credit ratingThe authors would like to thank all persons who collapse contributed right away or indirectly, peculiarly the control populate forc e who have toiled through the day and the dark in the endeavour towards a unwashed goal.
