====== Nivells i recàrregues d'heli líquid ======

Aquesta pàgina conté un resum dels nivells setmanals d'heli líquid als espectròmetres del SeRMN, i de les recàrregues efectuades
als **dos darrers anys.** Les dades de nivells i recàrregues d'anys anteriors, i les dades anuals de consum d'heli líquid es poden consultar a les pàgines,
  * [[manteniment_lhe_anys_anteriors | Registre històric de nivells i recàrregues d'heli líquid]] (de 2007 endavant)
  * [[consum_anual_lhe | Consum anual d'heli líquid]]

===== Instruccions del registre =====

  * Les recàrregues d'heli s'indiquen en **negreta**.
  * Afegeix les noves dades al capdamunt de la taula, de forma que estiguin en ordre cronològic invers i es vegin immediatament sense haver de baixar fins el final de la taula (els anys tenen moltes, 51 ó 52, setmanes!).
  * El format de les dates és YYYY-MM-DD, d'acord amb la recomanació del [[http://www.w3.org/QA/Tips/iso-date | World Wide Web Consortium (W3C)]].

===== 2021 =====

<WRAP important 100%>
  * **Avance DPX-360**
    * El nivell 0% del sensor del 360 se situa just per sobre de la bobina, i marca el nivell mínim d'heli per una recàrrega segura.
    * Calcular una estimació del nivell considerant un **consum setmanal del 5%.**
  * **Avance DRX 500**
    * Des de mitjans de 2020, després d'una recàrrega per sobre del 90%, quan el nivell baixa **es queda al 89%-90% durant tres setmanes** i després continua baixant.
  * **Avance II+ 600**
    * Després d'una recàrrega al 100%, les primeres setmanes el nivell d'heli roman constant o baixa molt poc a poc
