工作點(diǎn)反饋系統(tǒng)對(duì)同步輻射光源運(yùn)行穩(wěn)定性的提升(英文)
發(fā)布時(shí)間:2021-08-07 18:00
上海同步輻射裝置(SSRF)儲(chǔ)存環(huán)上目前已經(jīng)安裝了十臺(tái)插入元件(IDs)。在用戶時(shí)間,插入元件的間隙被反復(fù)地調(diào)整以進(jìn)行科學(xué)實(shí)驗(yàn)。雖然使用了插入件前饋系統(tǒng),但依然存在擾動(dòng)束流光學(xué)的殘余四極場(chǎng),它會(huì)導(dǎo)致束流橫向振蕩工作點(diǎn)的變化,進(jìn)而影響機(jī)器的性能和同步輻射光亮度的穩(wěn)定。為此,我們研發(fā)了一個(gè)工作點(diǎn)反饋系統(tǒng)來(lái)解決這個(gè)問(wèn)題,并且已經(jīng)在上海光源儲(chǔ)存環(huán)上投入了運(yùn)行,在兩周左右的運(yùn)行周期內(nèi),工作點(diǎn)的穩(wěn)定度達(dá)到了±0.001。這個(gè)反饋系統(tǒng)還有另一個(gè)重要功能,即可以根據(jù)監(jiān)控反饋系統(tǒng)校正電流的變化趨勢(shì)來(lái)判斷二極磁鐵電源和四極磁鐵電源是否存在慢漂問(wèn)題。為了驗(yàn)證這個(gè)工作點(diǎn)反饋的可行性,我們對(duì)使用反饋前后幾周的束流參數(shù)進(jìn)行了比較,包括儲(chǔ)存環(huán)注入效率、束流壽命、水平方向束斑尺寸以及β函數(shù)的變化情況(beta-beatings)。
