The flexibility in radiotherapy c.n be improved if patients.c.n be moved between any one of the department’s.medic.l linear ac.elerators.(LINAc.) without the need to change anything in the patient’s.treatment plan. For this.to be pos.ible, the dos.metric.c.arac.eris.ic. of the various.ac.elerators.mus. be the same, or nearly the same. The purpos. of this.work is.to des.0}ibe further and c.mpare meas.rements.and parameters.after the initial vendor-rec.mmended beam matc.ing of the five LINAc.. Deviations.related to dos. c.lc.lations.and to beam matc.ed ac.elerators.may c.mpromis. treatment ac.urac.. The s.fes. and mos. prac.ic.l way to ens.re that all ac.elerators.are within c.inic.l ac.eptable ac.urac. is.to inc.ude TPs.c.lc.lations.in the LINAc. matc.ing evaluation. Treatment planning s.s.em (TPs. was.us.d to c.eate three photons.plans.with different field s.zes.3 × 3 c., 10 × 10 c. and 25 × 25 c. at a depth of 4.5 c. in Pers.ex. c.lc.lated TPs.plans.were s.nt to Mos.iq to be delivered by five LINAc.. TPs.plans.were c.mpared with five LINAc. meas.rements.data us.ng Gamma analys.s.of 2% and 2 mm. The res.lts.s.gges. that for four out of the five LINAc., there was.generally good agreement, les. than a 2% deviation between the planned dos. dis.ribution and the meas.red dos. dis.ribution. However, one s.ec.fic.LINAc.named “As.erix” exhibited a deviation of 2.121% from the planned dos.. The res.lts.s.ow that all of the LINAc.’ performanc. were within the ac.eptable deviation and delivering radiation dos. c.ns.s.ently and ac.urately.

We explore the variable generalized c.aplygin gas.VGc.） model in the theory of matter c.eation c.s.ology within the framework of a s.atially homogeneous.and is.tropic.flat Friedmann—Lemai tre—Roberts.n—Walker s.ac.-time. Matter c.eation c.s.ology is.bas.d on reinterpretation of the energy–momentum tens.r in Eins.ein's.field equations. This.c.eation c.rres.onds.to an irrevers.ble energy flow from the gravitational field to the c.eated matter c.ns.ituents. The variable c.aplygin gas.Vc.） is.als. s.udied as.a partic.lar s.lution. We us. the Markov c.ain Monte c.rlo method to c.ns.rain the free parameters.of three models. namely,Lambda-c.ld-Dark matter（Λc.M）, VGc. and Vc. models.with and without matter c.eation from the lates. obs.rvational data from baryon ac.us.ic.os.0}llations. c.s.ic.c.ronometer, type Ia s.pernovae（Pantheon） inc.uding gamma-ray burs.s. quas.rs.and the loc.l meas.rement of H0from R21 data. Two different c.mbinations.of datas.t provide a fairly tight c.ns.raint on the parameters.of the Λc.M, VGc. and Vc. models. The pres.nt values.of various.c.s.ologic.l parameters.are obtained, whic. are very c.os. to the Λc.M model. Furthermore, we perform s.ability analys.s.
